readline() function in file handling in python by R4R Team

- readline() is a python function used in file handling which read the line of the file one by one.

Syntax-

f=open('myfile.txt','r')
f.readline()


program-

#write data in file in multiple lines
f=open("myfile.txt",'w')
f.write("firstnsecondnthirdnfourthnfive")
f.close()

#read file line by line
f=open("myfile.txt",'r')
print(f.readline())
print(f.readline())
print(f.readline())
print(f.readline())
print(f.readline())
f.close()

output-

first
second
third
fourth
five

-In this program, initially we write into file in multiple lines then by f.readline() return first line and goto second line automatically, so we again print second line and it continue read line one by one and goes to next line.
