In Python, is read() , or readlines() faster?

Question

I want to read a huge file in my code. Is read() or readline() faster for this. How about the loop:

for line in fileHandle

Answer 1

Neither. Both of them will read the content into memory. In case of big files, iterating over the file object only loads one line of your file at a time and is perhaps a good way to deal with the contents of a huge file.
