Using “readlines()” twice in a row

Question

I\'m trying to do something like this:

Lines = file.readlines()
# do something
Lines = file.readlines()  

but the second time Lines

Answer 1

In order to not have to reset every time by using seek method again and again, use the readlines method, but you must store it in variable like this example below:

%%writefile test.txt
this is a test file!
#open it
op_file = open('test.txt')
#read the file
re_file = op_file.readlines()
re_file
#output
['this is a test file!']
# the output still the same
re_file
['this is a test file!']
