Question

Python Programming 4th Edition: Need help writing this program below. I get an error message that says that name is not defined when running the program below.

My solution:

def main():

filename = "text.txt"

contents=f.read()

upper_count=0
lower_count=0
digit_count=0
space_count=0
for i in contents:
if i.isupper():
upper_count+=1
elif i.islower():
lower_count+=1
elif i.isdigit():
digit_count+=1
elif i.isspace():
space_count+=1
print("Upper case count in the file is",upper_count)
print("Lower case count in the file is",lower_count)
print("Digit count in the file is",digit_count)
print("Space_count in the file is",space_count)
if __name__=="__main__":
main()

Hey here is answer to your question.

In case of any doubt comment below. Please UPVOTE if you Liked the answer.

See error in your code was you are not reading the file correctly so the text will not be processed because there is no content in filename variable.

I fix it now it should work perfectly.

def main():
  
   filename = open("text.txt",'r')
  
   contents=filename.read()
  
   upper_count=0
   lower_count=0
   digit_count=0
   space_count=0
   for i in contents:
       if i.isupper():
           upper_count+=1
       elif i.islower():
           lower_count+=1
       elif i.isdigit():
           digit_count+=1
       elif i.isspace():
           space_count+=1
   print("Upper case count in the file is",upper_count)
   print("Lower case count in the file is",lower_count)
   print("Digit count in the file is",digit_count)
   print("Space_count in the file is",space_count)
if __name__=="__main__":
   main()
