Reading a file line by line into elements of an array in Python [duplicate]
testsite_array = []with open('topsites.txt') as my_file: for line in my_file: testsite_array.append(line)
This is possible because Python allows you to iterate over the file directly.
Alternatively, the more straightforward method, using f.readlines()
:
with open('topsites.txt') as my_file: testsite_array = my_file.readlines()
In python you can use the readlines
method of a file object.
with open('topsites.txt') as f: testsite_array=f.readlines()
or simply use list
, this is same as using readlines
but the only difference is that we can pass an optional size argument to readlines
:
with open('topsites.txt') as f: testsite_array=list(f)
