How to add list values into a JSON file. Here is my code :
import os,string
drives_a = [chr(x) + ':' for x in range(65, 90) if os.path.exists(chr(x) + ':')]
Does this work for you?
import json
lst = [1,2,3]
file_name = 'test.json'
with open(file_name, 'w') as f:
f.write(json.dumps(lst))

from pathlib import Path
from csv import reader
base_folder = Path(__file__).parent.resolve()
csvfilewrite = open(str(base_folder) + "/ourresults.csv", 'w')
csvfilewrite.write("")
csvfilewrite.close()
csvfileapp = open(str(base_folder) + "/ourresults.csv", 'a')
ListOfVals = ['.2.', '[89....1]']
def csvtolist(filename):
with open(filename) as csvfile:
csv_read = reader(csvfile, delimiter=',')
for row in csv_read:
print(row)
ListOfVals.append(str(row).split(",")[0])
return ListOfVals
def returnnumbers(Array): #Array Elements added from the Csv look like this "['2']"
newstr = ''
for i in Array:
for j in range(0, len(i)):
if i[j].isdigit():
newstr += i[j]
newstr += ", "
return newstr
for i in range(1, 21):
csvfileapp.write(str(i) + "\n")
csvtolist(str(base_folder) + "/ourresults.csv")
print(returnnumbers(ListOfVals) + "ugh")
csvfileapp.close()
i use the csvfilewrite variable to clear the csv file when the program opens.
The output i get if i keep it in write mode is
2, 891, ugh
if i either set the csvfilewrite in append mode, or comment out csvfilewrite, the csvfiletolist function will work as i intend. Heres a recreation of what shows up in the terminal in vs code:
...
['20']
2, 891, 1, 2, 3, 4 ... 20, ugh
Why does the csvfiletolist function break like this?
I am working on a text file right now that is called "dracula.txt", and I have to do the following in python:
Save words that occur no more than 3 times in descending order in a file called less_common_words.txt. Each word with its count should be saved on a separate line.
I would appreciate any help! I've been working on this for too long.
I have already tokenized my file and counted the words. This is my code so far:
file = open("C:/Users/17733/Downloads/dracula.txt", 'r', encoding = 'utf-8-sig')
data = file.read()
data
data_list = data.split('\n')
data_list
new_list = []
for i in data_list:
if i !='':
ans_here = i.split(' ')
new_list.extend(ans_here)
new_list
import string
import re
puncs = list(string.punctuation)
puncs.append('"')
puncs.append('[')
puncs.append('.')
puncs.append('-')
puncs.append('_')
#append each seperately
new_2 = []
for i in new_list:
for p in puncs:
if p in i:
i_new = i.replace(p, ' ')
new_2.append(i_new)
new_2
new_2 = [i.replace(' ', ' ').strip().lower() for i in new_2]
new_2
from pathlib import Path
from collections import Counter
import string
filepath = Path('test.txt')
output_filepath = Path('outfile.txt')
# print(filepath.exists())
with open(filepath) as f:
content = f.readlines()
word_list = sum((
(s.lower().strip('\n').translate(str.maketrans('', '', string.punctuation))).split(' ')
for s in content
), [])
less_common_words = sorted([
key for key, value in Counter(word_list).items() if value <= 3
],reverse=True)
with open(output_filepath, mode='wt', encoding='utf-8') as myfile:
myfile.write('\n'.join(less_common_words))
This should exactly be what you need- I fixed my previous error by flattening the entire txt into a 2d list:
book_open = open('frankenstein.txt', 'r').readlines()
beauty_book = [i.split() for i in book_open]
flatten = []
for sublist in beauty_book:
for val in sublist:
flatten.append(val)
foo = 0
for i in flatten:
list_open = open('less_common_words.txt', 'r').readlines()
beauty_list = [i.replace('\n', '') for i in list_open]
count = flatten.count(flatten[foo])
compile = str((flatten[foo], count))
if count <= 3:
if compile not in beauty_list:
file = open('less_common_words.txt', 'a+')
file.write('\n'+compile)
file.close()
foo += 1
I have the following code which prints the object as CSV:
title = ['Username', 'Name', 'Job']
for x in title:
print(x, end =",")
for d in data:
line = d.get_username() + "," + d.get_name() + "," + d.get_role()
print(line)
I get:
Username,Name,Job
rob,robert,developer
danny21,danny,developer
I want to print the same data as JSON in order to get:
[
{
"Username":"rob",
"Name":"robert",
"Job":"developer"
},
{
"Username":"danny21",
"Name":"danny",
"Job":"developer"
}
]
From previous topics I learn that we can use json.dumps but I'm not sure if it helps in this case.
What is the proper way to achieve it?
You could simply do:
l = []
for d in data:
user_dictionary = {}
user_dictionary[title[0]] = d.get_username()
user_dictionary[title[1]] = d.get_name()
user_dictionary[title[2]] = d.get_role()
l.append(user_dictionary)
to get a json like file.
You can also avoid appending and do:
def get_user_data(user):
user_dictionary = {}
user_dictionary[title[0]] = d.get_username()
user_dictionary[title[1]] = d.get_name()
user_dictionary[title[2]] = d.get_role()
return user_dictionary
l = list(map(get_user_data, data))
You can use json.dump to dump l in a file
import json
with open('data.json', 'w') as outfile:
json.dump(l, outfile)
I have a file that consists of a single line:
a,x,b,c,d,e
I want to convert this into
a,x,b,x,c,x,d,x,e,x
Is there any easy way to achieve this with python?
my_file = open(filename)
data = my_file.read()
data = data.split(',')
str = ''
for each in data:
if each != 'x':
str += each + ',' + 'x' + ','
str= str.strip(',')
print str
import re
s = open(filename).read()
open(filename, 'w').write(',x,'.join(re.findall(r'[a-wyz]', s)) + ',x\n')
The problem I am having at this point in time (being new to Python) is writing strings to a text file. The issue I'm experiencing is one where either the strings don't have linebreaks inbetween them or there is a linebreak after every character. Code to follow:
import string, io
FileName = input("Arb file name (.txt): ")
MyFile = open(FileName, 'r')
TempFile = open('TempFile.txt', 'w', encoding='UTF-8')
for m_line in MyFile:
m_line = m_line.strip()
m_line = m_line.split(": ", 1)
if len(m_line) > 1:
del m_line[0]
#print(m_line)
MyString = str(m_line)
MyString = MyString.strip("'[]")
TempFile.write(MyString)
MyFile.close()
TempFile.close()
My input looks like this:
1 Jargon
2 Python
3 Yada Yada
4 Stuck
My output when I do this is:
JargonPythonYada YadaStuck
I then modify the source code to this:
import string, io
FileName = input("Arb File Name (.txt): ")
MyFile = open(FileName, 'r')
TempFile = open('TempFile.txt', 'w', encoding='UTF-8')
for m_line in MyFile:
m_line = m_line.strip()
m_line = m_line.split(": ", 1)
if len(m_line) > 1:
del m_line[0]
#print(m_line)
MyString = str(m_line)
MyString = MyString.strip("'[]")
#print(MyString)
TempFile.write('\n'.join(MyString))
MyFile.close()
TempFile.close()
Same input and my output looks like this:
J
a
r
g
o
nP
y
t
h
o
nY
a
d
a
Y
a
d
aS
t
u
c
k
Ideally, I would like each of the words to appear on a seperate line without the numbers in front of them.
Thanks,
MarleyH
You have to write the '\n' after each line, since you're stripping the original '\n';
Your idea of using '\n'.join() doesn't work because it will use\n to join the string, inserting it between each char of the string. You need a single \n after each name, instead.
import string, io
FileName = input("Arb file name (.txt): ")
with open(FileName, 'r') as MyFile:
with open('TempFile.txt', 'w', encoding='UTF-8') as TempFile:
for line in MyFile:
line = line.strip().split(": ", 1)
TempFile.write(line[1] + '\n')
fileName = input("Arb file name (.txt): ")
tempName = 'TempFile.txt'
with open(fileName) as inf, open(tempName, 'w', encoding='UTF-8') as outf:
for line in inf:
line = line.strip().split(": ", 1)[-1]
#print(line)
outf.write(line + '\n')
Problems:
the result of str.split() is a list (this is why, when you cast it to str, you get ['my item']).
write does not add a newline; if you want one, you have to add it explicitly.
