Help needed on readline() in Python 3.0

Question

Consider the following code:
# Line by Line Printer
fh = open('mbox.txt')
fl = fh.readline(10)
for line in fl:
print(line)
I intend to print the first 10 lines of the txt file, but the output is only the first line. What's the problem? Should I switch to readlines() ?

Answer 1

with open("Filename",'r') as f:
for i in range(10):
print(f.readline())
