Remove all the lines that contain the character `a’ in a file and write it to another file.

For Basics on File operations please do read our previous blog:

Python Program to read a file line by line and print it on the console

With the above inputs, replacing ‘a’ in all the lines and printing it to another file our objective will be satisfied.

write()

write(string) : Inserts the string in a single line in the text file.

File_object.write(line)

So to remove all the lines that contain the character `a’ in a file and write it to another file we can revise the code as follows:

try:
 filepath = ‘’#path of file to be read-sepeated by //
 with open(filepath) as fp,open(‘’, ‘w’) as outfile:#new file path
   for cnt, line in enumerate(fp):
    line=line.replace(‘a’,’’)
    outfile.write(line)
finally:
 fp.close()
