There's something with that last function that is really tripping me up. I keep getting errors. I know aDictionary is not defined but I do not even know what to define it as! Any of you guys have an idea? Thanks.

with open("some_file.txt","W") as f:
print >> f, "Something goes here!"
its hard to say without your errors. .. but you almost certainly need to have aDictionary defined
also probably something like
def DisplayCounts(InputFile):
print "\n"
numCount = 0
dotCount = 0
commaCount = 0
lineCount = 0
wordCount = 0
with open(InputFile, 'r') as f:
for line in f:
wordCount+=len(line.split())
lineCount+=1
for char in line:
if char.isdigit() == True:
numCount+=1
elif char == '.':
dotCount+=1
elif char == ',':
commaCount+=1
return dict(numbers=numCount,
comma=commaCount,
dot=dotCount,
line=lineCount,
word=wordCount)
result = DisplayCounts("someinput.txt")
print result

Why is my write to file function overriding my previous file text?

I'm trying to add user entered data to a tuple, then write that tuple on a line in my text file. I'm doing something wrong because only the last call is added to the txt file. Here's my functions:
def write_to_file(tuple1):
with open('student_info.txt', 'w') as f:
f.write(' '.join(x for x in tuple1))
f.write("\n")
def get_student_info(student_name):
tuple1 = ()
tuple1 = tuple1 + (student_name,)
print("\nScores for " + student_name)
print("Enter a test score (or enter Stop to stop):")
count = 2
test_score = input("Test score 1: ")
tuple1 = tuple1 + (test_score,)
while not test_score == "stop" and not test_score == "Stop":
test_score = input("Test score " + str(count) + ": ")
count = count + 1
tuple1 = tuple1 + (test_score,)
last_item = len(tuple1) - 1
tuple1 = tuple1[:last_item]
write_to_file(tuple1)
def read_from_file():
with open('student_info.txt', 'r') as f:
f_contents = f.read()
print(f_contents, end=" ")
And here's my calls in the main section:
open("student_info.txt", "w").close()
student_name = ""
get_student_info("Jenny: ")
get_student_info("Dave: ")
get_student_info("Sammy: ")
get_student_info("Brooke: ")
read_from_file()
My student_info.txt just ends up reading "Brooke:" and then the data added to the tuple on the last call.
If you want to append to a file you need to change the ‘w’ to an ‘a’ for append when you want to write to the file.

Python - Every other letter in a string capitalized within a loop where the data was handed down from a copied list of user input

I was instructed to have a user input at least 8 words into a list and then perform various manipulations to the data within the list. One of the manipulations it asks me to do is to create a loop that makes every other letter in the strings capitalized (hElLo WoRlD.) For better readability, I left out the other manipulations that I have done to the code.
import sys
def main():
words = []
wordCount = 0
userWord = input("Enter at least 8 words or 'bye' to leave the program: ").split(' ')
while True:
if len(userWord)<8:
print("Please print at least 8 words, try again.")
sys.exit()
elif wordCount >= 8 and userWord[wordCount] != 'bye':
words.append(userWord[wordCount])
wordCount = wordCount + 1
else:
break
every_other (userWord)
def every_other(words):
words6 = words.copy()
st = ""
for i in range(len(words6)):
if (i%2) == 0:
st += words6[i].upper()
else:
st += words6[i]
print ('This is your list with every other letter capitalized: ', words6)
return st
main()
I am not getting any error messages but the code doesn't seem to be running starting at def every_other.
You'll have to print the function every_other as it returns a string:
import sys
def main():
words = []
wordCount = 0
userWord = input("Enter at least 8 words or 'bye' to leave the program: ").split(' ')
while True:
if len(userWord)<8:
print("Please print at least 8 words, try again.")
sys.exit()
elif wordCount >= 8 and userWord[wordCount] != 'bye':
words.append(userWord[wordCount])
wordCount = wordCount + 1
else:
break
print('This is your list with every other letter capitalized: ', every_other(userWord))
def every_other(words):
words6 = words.copy()
st = ""
for i in range(len(words6)):
if (i%2) == 0:
st += words6[i].upper()
else:
st += words6[i]
return st
#print ('This is your list with every other letter capitalized: ', words6) # This will never run as the function has already returned
main()
If you want to capitalize every second character:
import sys
def main():
words = []
wordCount = 0
userWord = input("Enter at least 8 words or 'bye' to leave the program: ").split(' ')
while True:
if len(userWord)<8:
print("Please print at least 8 words, try again.")
sys.exit()
elif wordCount >= 8 and userWord[wordCount] != 'bye':
words.append(userWord[wordCount])
wordCount = wordCount + 1
else:
break
print('This is your list with every other letter capitalized: ', every_other(userWord))
def every_other(words):
st = ""
new_st = ""
for w in words:
st+=w
print(str(st))
for count, val in enumerate(st):
if (count % 2) == 0:
val = val.upper()
new_st+=val
return new_st
main()

How do I make my decrypt code work?

I created this code that encrypts text but when it tries to decrypt I get a:
builtins.ValueError: chr() arg not in range(0x110000)
Any help in making the decryption code work properly would be much appreciated!
input1 = input("enter key word: ")
input2 = input1[:1]
key = ord(input2)
num_count = 32
dic= {}
while num_count <= 126:
resultant = float(num_count*key*565)
dic[num_count] = resultant
num_count += 1
string = input("Please enter text: ")
num_list = ""
for i in (string):
number = int(ord(i))
value = (dic[number])
number_value = str(value)
final_value = number_value+" "
num_list += final_value
print("Encrypted text is", num_list)
num_count3 = 0
decrypt_text = ""
string_len = len(num_list)
characters = []
localChar = ""
for i in num_list:
if i != " ":
localChar = localChar + i
elif i == " ":
characters.append(localChar)
localChar = ""
num_count3 = 0
list_len = len(characters)
while num_count3 < list_len:
value = float(characters[num_count3])
valuel = int(value/key/54734)
value2 = round(value)
de_char = chr(value2)
decrypt_text += de_char
num_count3 += 1
print(decrypt_text)
going to be honest, code was all over. But I hope this helps.
Issue:
num_count3 = 0 first instance not use
string_len = len(num_list) not used
int(value/key/54734) should be round(value/key/565) < your issue +
value2 = round(value) should be value2 = int(valuel)
And lots of clean up + Functions are great!
def encrypt(key, input1):
num_count = 32
dic = {i:float(i*key*565) for i in range(num_count,127)}
string = input("Please enter text: ")
num_list = ' '.join([str(dic[ord(i)]) for i in string])
print("Encrypted text is", num_list)
return num_list
def decrypt(key, num_list):
characters = num_list.split()
decrypt_text = ""
num_count3 = 0
list_len = len(characters)
while num_count3 < list_len:
value = float(characters[num_count3])
valuel = (value/key/565)
value2 = int(round(valuel))
de_char = chr(value2)
decrypt_text += de_char
num_count3 += 1
print(decrypt_text)
if __name__ == "__main__":
input1 = input("enter key word: ")
key = ord(str(input1[:1]))
print key
result = encrypt(key, input1)
decrypt(key, result)

You need to strip the newlines off each of the dictionary lines. In other words:
for word in a:
c,b = word.rstrip().split(",")
dictionary[c] = b
When you iterate a file like for word in a:, you get a string for each line in the file, including the newline at the end. So, your dictionary ends up full of entries like 'y': 'why\n' instead of 'y': 'why'.
You can strip the trailing newline from word.split(",") by calling str.strip.
word.strip().split(",")
You can also use read() to load the contents of the file which doesn't include newlines.

Python file appears to be empty after a function

Code:
import os, csv
def menu():
print("Welcome to da sporty ting" + "\n" + "Menu options: " + "\n")

lines = f.read().splitlines()

Text file sample:
1,2,3,0,0
0,0,3,2,1
1,0,0,3,2
1,0,0,2,3
0,1,2,3,0
Currently I have a problem where after file_validity(), the text file just appears to have loaded up as empty as when I re-open the file in the next function, it prints lines as empty. file_validity() just deletes the file, and rewrites the valid votes. As you can see I have tried to find out where the trouble lies. I believe the truncate and seek functions seem to be causing some trouble but I am not sure if this is true. And if it were to be the case, how to fix it.
Any help?
Thanks in advance.
