I want to read the file line by line and save it to the array

fname = "file path"

#1.
with open(fname) as f:
    lines = f.readlines()

#2.
lines = [line.rstrip('\n') for line in open(fname)]

#3.
with open(fname, "r") as ins:
    lines = []
    for line in ins:
        array.append(line)

#4.
lines = tuple(open(fname, 'r'))
