Python skipping one line after reading another [duplicate]

Question

I am trying to read a file and write its contents in another file.

with open (inputFile, "r+") as file:
    with open (outputFile, "w+") as f:
        for line in file:
            data = file.readline()
            f.write(data)
    f.close()
file.close() 

This is the code I used, but it seems to be skipping lines, so, if I have something like this in the input file:

'First line'
'Second line'
'Third line'
'Fourth line'

I get this in the outputFile:

'Second line'
'Fourth line'

What am I doing wrong?

Answer 1

for line in file iterates over each line already. data = file.readline() will yield another one from the file. Use one or the other.
