what is the difference between read() and readlines()?

Answer 1

Read method reads the whole file as a single string while readlines segregates each of the line in the file and you then can later on call them line by line.

Answer 2

Hamid Ashraf what if i used readline first then i used read()? will read() read all file include first line?

Answer 3

That depends on your code. If f is an open file you can apply any method in any sequence provided that you are saving their output in different variable.

Answer 4

Hamid Ashraf thank you :)
