readlines() to get a list of lines by reading from a file in Python

readlines()

readlines(limit)

limit : optional upper limit of bytes returned.
Output is a list of lines present inside the file.

fob=open('data.txt','r')
print(fob.readlines())
fob.close()

Output is here ( used the data.txt file given at file read() )

['This is first line\n', 'This is second line\n', 'This is third line\n', 'This is fourth line']

Using limit

fob=open('data.txt','r')
print(fob.readlines(10)) # ['This is first line\n']
fob.close()

We can use output as an iterator.

fob=open('data.txt','r')
my_data=(fob.readlines())
print(type(my_data)) # 
for x in my_data:
    print(x)
fob.close()

Output is here


This is first line

This is second line

This is third line

This is fourth line
