Open a text file and transform is to that the first letter is capital and rest is lowercase

Question

I have a text file that reads

I
BLESS 
THE 
RAINS
DOWN
IN 
AFRICA

and I need it to be transformed where all the first letters are capitalized and the rest lowercase. The second part is I need this transformed text to be written into a new text document.

text_file = open('lyrics.txt','r')

Answer 1

You can use the title method on the contents of the file

with open("lyrics.txt") as f:
    s = f.read().title()

with open("lyrics.txt", "w") as f:
    f.write(s)

You could fit this all into one context manager, but I find the above more readable than

with open("lyrics.txt", "r+") as f:
    s = f.read().title()
    f.seek(0)
    f.write(s)

Answer 2

Is this what you want?:

with open('file.txt','r') as f:
   newl = []
   l = f.readlines()
   for i in l:
      newl.append(str(i[0]+i[1:].lower()).strip())
with open('new.txt','w') as f2:
   for i in newl:
      f2.write(i+'\n')
