everyone.
I have some problems with calculating gcskews in python.
My 2 major inputs are fasta file and bed file.
Bed file has columns of gn(0), gene_type(1), gene name(2), chromosome(3), strand(4), num(5), start(6).(These numbers are index numbers in python.) Then I am trying to use some functions which can calculate gcskews of sense and antisense strand from the start site of each gene. The window is 100bp and these are the functions.
import re
import sys
import os
# opening bed file
content= []
with open("gene_info.full.tsv") as new :
for line in new :
content.append(line.strip().split())
content = content[1:]
def fasta2dict(fil):
dic = {}
scaf = ''
seq = []
for line in open(fil):
if line.startswith(">") and scaf == '':
scaf = line.split(' ')[0].lstrip(">").replace("\n", "")
elif line.startswith(">") and scaf != '':
dic[scaf] = ''.join(seq)
scaf = line.split(' ')[0].lstrip(">").replace("\n", "")
seq = []
else:
seq.append(line.rstrip())
dic[scaf] = ''.join(seq)
return dic
dic_file = fasta2dict("full.fa")
# functions for gc skew
def GC_skew_up(strand, loc, seq, window = 100) : # need -1 for index
values_up = []
loc = loc - 1
if strand == "+" :
sp_up = seq[loc - window : loc]
g_up = sp_up.count('G') + sp_up.count('g')
c_up = sp_up.count('C') + sp_up.count('c')
try :
skew_up = (g_up - c_up) / float(g_up + c_up)
except ZeroDivisionError:
skew_up = 0.0
values_up.append(skew_up)
elif strand == "-" :
sp_up = seq[loc : loc + window]
g_up = sp_up.count('G') + sp_up.count('g')
c_up = sp_up.count('C') + sp_up.count('c')
try :
skew_up = (c_up - g_up) / float(g_up + c_up)
except ZeroDivisionError:
skew_up = 0.0
values_up.append(skew_up)
return values_up
def GC_skew_dw(strand, loc, seq, window = 100) :
values_dw = []
loc = loc - 1
if strand == "+" :
sp_dw = seq[loc : loc + window]
g_dw = sp_dw.count('G') + sp_dw.count('g')
c_dw = sp_dw.count('C') + sp_dw.count('c')
try :
skew_dw = (g_dw - c_dw) / float(g_dw + c_dw)

except ZeroDivisionError:

values_dw.append(skew_dw)
return values_dw
As I said, I want to calculate the gcskews for 100bp of strands from the start site of genes.
Therefore, I made codes that get the chromosome name from the bed file and get the sequence data from the Fasta file.
Then according to gene name and strand information, I expected that codes will find the correct start site and gcskew for 100bp window will be calculated.
However, when I run this code, gcskew of - strand is wrong but + strand is correct. (I got correct gcskew data and I used it.)
Gcskews are different from the correct data, but I don't know what is the problem.
Could anyone tell me what is the problem of this code?
Thanks in advance!
window = 100
gname = []
up = []
dw = []
for match in content :
seq_chr = dic_file[str(match[3])]
if match[4] == "+" :
strand = match[4]
new = int(match[6])
sen_up = GC_skew_up(strand, new, seq_chr, window = 100)
sen_dw = GC_skew_dw(strand, new, seq_chr, window = 100)
gname.append(match[2])
up.append(str(sen_up[0]))
dw.append(str(sen_dw[0]))
if match[4] == "-" :
strand = match[4]
new = int(match[6])
an_up = GC_skew_up(strand, new, seq_chr, window = 100)
an_dw = GC_skew_dw(strand, new, seq_chr, window = 100)
gname.append(match[2])
up.append(str(an_up[0]))
dw.append(str(an_dw[0]))
tot = zip(gname, up, dw)

Just attempting to return values from a defined function. When calling the function first and attempting to print the return values I receive "[variable] not defined". However, if I run "print(qb_stat_filler())" it prints the results in a tuple. I need the individual variables returned to use in a separate function.
For Example
print(qb_stat_filler())
outputs: (0, 11, 24, 24.2024, 39.1143, 293.0, 1.9143000000000001, 0.2262, 97.84333355313255)
but when trying
qb_stat_filler()
print(cmp_avg)
print(att_avg)
outputs: NameError: name 'cmp_avg' is not defined
Process finished with exit code 1
I've tried establishing the variables outside of the function, then passing and returning them and that did not work either. Any thoughts?
def qb_stat_filler():
n_input = input('Player name: ')
t_input = input('Players team: ')
loc_input = input('H or #: ')
o_input = input('Opponent: ')
# convert index csv to dictionary of player values
q = pd.read_csv('Models\\QB Indexes\\QBname.csv')
q = q[['Player', 'Num']]
qb_dict = dict(q.values)
name = qb_dict.get('{}'.format(n_input))
t = pd.read_csv('Models\\QB Indexes\\Tmname.csv')
t = t[['Tm', 'Num']]
tm_dict = dict(t.values)
team = tm_dict.get('{}'.format(t_input))
loc = 0
if loc_input == '#':
loc = 0
elif loc_input == 'H':
loc = 1
z = pd.read_csv('Models\\QB Indexes\\Oppname.csv')
z = z[['Opp', 'Num']]
opp_dict = dict(z.values)
opp = opp_dict.get('{}'.format(o_input))
*there are several lines of code here that involve SQL
queries and data cleansing*
cmp_avg = (cmp_match + cmpL4) / 2
att_avg = (patt_match + pattL4) / 2
pyds_avg = (py_match + pydsL4) / 2
ptd_avg = (ptdL4 + ptd_match) / 2
int_avg = (intL4 + int_match) / 2
qbr_avg = (qbr_match + qbrL4) / 2
return name, team, opp, cmp_avg, att_avg, pyds_avg, ptd_avg,
int_avg, qbr_avg
qb_stat_filler()
You might consider:
def qb_stat_filler():
stats = {}
...
stats['name'] = name
z = z[['Opp', 'Num']]
opp_dict = dict(z.values)
stats['opp'] = opp_dict.get('{}'.format(o_input))
...
stats['cmp_avg'] = (cmp_match + cmpL4) / 2
stats['att_avg'] = (patt_match + pattL4) / 2
stats['pyds_avg'] = (py_match + pydsL4) / 2
stats['ptd_avg'] = (ptdL4 + ptd_match) / 2
stats['int_avg'] = (intL4 + int_match) / 2
stats['qbr_avg'] = (qbr_match + qbrL4) / 2
return stats
...
stats = qb_stat_filler()
print(stats['cmp_avg'])

The
ValueError: substring not found
occurs when you try to find the index of a substring in a string which does not contain it in the specified (or default) section, using the index function.
The index method takes 3 parameters:
value
start
end
and it searches for the value between start and end.
So, the error occurred because the substring was not found in the section where it was searched for. The line of
OS_nextIndex = originalScript.index(wordString,tagEnd)+len(wordString)
searches for wordString, starting from tagEnd and searches for the likes of
<span>yourwordstring</span>
, but in your case it was not found. You can do one of the following to solve the issue:
you can fix your input if it should always have a match for the search
you can handle the error when the index throws the error
you can use find instead, see https://bobbyhadz.com/blog/python-valueerror-substring-not-found
Note that find also has three parameters, as you can read from https://www.w3schools.com/python/ref_string_find.asp
I'm trying to standardize street address by converting the abbreviations to the full word (e.g. RD - Road). I created many lines to account for different spellings and ran into an issue where one replace code overrode another one
import pandas as pd
mydata = {'Street_type': ['PL', 'pl', 'Pl', 'PLACE', 'place']}
mydata = pd.DataFrame(mydata)
mydata['Street_type'] = mydata['Street_type'].replace('PL','Place',regex=True)
mydata['Street_type'] = mydata['Street_type'].replace('pl','Place',regex=True)
mydata['Street_type'] = mydata['Street_type'].replace('Pl','Place',regex=True)
mydata['Street_type'] = mydata['Street_type'].replace('PLACE','Place',regex=True)
mydata['Street_type'] = mydata['Street_type'].replace('place','Place',regex=True)
Instead of Place, I got Placeace. What is the best way to avoid this error? Do I write a if-else statement or any function? Thanks in advance!
Among other problems, you have overlapping logic: you fail to check that the target ("old") string is a full word before you replace it. For instance, with the input type of "PLACE", you trigger both the first and third replacements, generating PlaceACE and then PlaceaceACE before you get to the condition you wanted.
You need to work through your tracking and exclusion logic carefully, and then apply only one of the replacements. You can check the length of the street_type and apply the unique transition you need for that length.
If you're trying to convert a case statement, then you need to follow that logic pattern, rather than the successive applications you coded. You can easily look up how to simulate a "case" statement in Python.
Also consider using a translation dictionary, such as
type_trans = {
"pl": "Place",
"Pl": "Place",
"PLACE": "Place",
...
}
Then your change is simply
mydata['Street_type'] = type_trans[mydata['Street_type']]
Also, you might list all of the variants in a tuple, such as:
type_place = ("PL", "Pl", "pl", "PLACE", "place")
if mydata['Street_type'] in type_place
mydata['Street_type'] = "Place"
... but be sure to generalize this properly for your entire list of street types.
You can do this correctly with a single pass if you use a proper regex here, e.g. use word boundaries (\b):
In [11]: places = ["PL", "pl", "Pl", "PLACE", "Place", "place"]
In [12]: mydata.Street_type
Out[12]:
0 PL
1 pl
2 Pl
3 PLACE
4 place
Name: Street_type, dtype: object
In [13]: mydata.Street_type.replace("(^|\b)({})(\b|$)".format("|".join(places)), "Place", regex=True)
Out[13]:
0 Place
1 Place
2 Place
3 Place
4 Place
Name: Street_type, dtype: object

Hello now im working on my project. I want to get candidate of text block by using algorithm below.
My input is a csv document which contain :
HTML column : the html code in a line
TAG column : the tag of html code in a line
Words : the text inside the tag in aline
TC : the number of words in a line
LTC : the number of anchor words in a line
TG : the number of tag in a line
P : the number of tag p and br in a line
CTTD : TC + (0.2*LTC) + TG - P
CTTDs : the smoothed CTTD
This is my algorithm to find candidate of text block. I make the csv file into dataframe using pandas. I am using CTTDs,TC and TG column to find the candidate.
from ListSmoothing import get_filepaths_smoothing
import pandas as pd
import numpy as np
import csv
filenames = get_filepaths_smoothing(r"C:\Users\kimhyesung\PycharmProjects\newsextraction\smoothing")
index = 0
for f in filenames:
file_html=open(str(f),"r")
df = pd.read_csv(file_html)
#df = pd.read_csv('smoothing/Smoothing001.csv')
news = np.array(df['CTTDs'])
new = np.array(df['TG'])
minval = np.min(news[np.nonzero(news)])
maxval = np.max(news[np.nonzero(news)])
j = 0.2
thetaCTTD = minval + j * (maxval-minval)
#maxGap = np.max(new[np.nonzero(new)])
#minGap = np.min(new[np.nonzero(new)])
thetaGap = np.min(new[np.nonzero(new)])
#print thetaCTTD
#print maxval
#print minval
#print thetaGap
def create_candidates(df, thetaCTTD, thetaGAP):
k = 0
TB = {}
TC = 0
for index in range(0, len(df) - 1):
start = index
if df.ix[index]['CTTDs'] > thetaCTTD:
start = index
gap = 0
TC = df.ix[index]['TC']
for index in range(index + 1, len(df) - 1):
if df.ix[index]['TG'] == 0:
continue
elif df.ix[index]['CTTDs'] <= thetaCTTD and gap >= thetaGAP:
break
elif df.ix[index]['CTTDs'] <= thetaCTTD:
gap += 1
TC += df.ix[index]['TC']
if (TC < 1) or (start == index):
continue
TB.update({
k: {
'start': start,
'end': index - 1
}
})
k += 1
return TB
def get_unique_candidate(TB):
TB = tb.copy()
for key, value in tb.iteritems():
if key == len(tb) - 1:
break
if value['end'] == tb[key+1]['end']:
del TB[key+1]
elif value['start'] < tb[key+1]['start'] < value['end']:
TB[key]['end'] = tb[key+1]['start'] - 1
else:
continue
return TB
index += 1
stored_file = "textcandidate/textcandidate" + '{0:03}'.format(index) + ".csv"
tb = create_candidates(df, thetaCTTD, thetaGap)
TB = get_unique_candidate(tb)
filewrite = open(stored_file, "wb")
df_list = []
for (k, d) in TB.iteritems():
candidate_df = df.loc[d['start']:d['end']]
candidate_df['candidate'] = k
df_list.append(candidate_df)
output_df = pd.concat(df_list)
output_df.to_csv(stored_file)
writer = csv.writer(filewrite, lineterminator='\n')
filewrite.close
ThetaCTTD is 10.36 and thethaGap is 1.
The output is
The output means there are 2 candidates of text block . First the candiate of text block start from line number 215 and end line number 225 (like the pict bellow). And the other candidate of text block start from line number 500 and end line number 501.
My question is how to save the output into csv and not only the number of line but the range of the text block and the others column will appear as the output too?
My expected output is like the screenshot of candidate text block is like this one
Assuming your output is a list of dictionaries:
pd.concat([df.loc[d['start']:d['end']] for (k, d) in TB.iteritems()])
Note that we slice by label, so d['end'] will be included.
Edit: add the candidate number in a new column.
It's cleaner to write a loop than to do two concat operations:
df_list = []
for (k, d) in TB.iteritems():
candidate_df = df.loc[d['start']:d['end']]
candidate_df['candidate'] = k
df_list.append(candidate_df)
output_df = pd.concat(df_list)
It's also faster to concatenate all dataframes at once at the end.
This small scripts makes exactly what I need.

It enters in a configuration file and replaces sequentially the input parameters according to the lists that are accessed by the loop indexes. It is simple a combination of all the three parameters between each other.
# Input file
param1 = 1 # --- Should be [1,2,3]
param2 = 1 # --- Should be [1,2,3]
param3 = 1 # --- Should be [1,2,3]
The problem is that his big brother is not behaving like it. When it loops through the lists, it gets lost in scheme = 2 and puts dissp_scheme = 2 (freezed) when it should be dissp_scheme = 1. I printed out every single variable that goes inside the function replaceAll marked with comments but when I turn on the other calls it mess up everything. Here is the script.
