Reading File Operation in Python

0 Comments

This tutorial will cover another function of file handling i.e. Reading a file.

For reading a file we need to first open using ‘r’ mode which is used for reading.

file = open("abc.text", "r")
print (file.read())
print(file.readline())

read() returns whole string but we can also specify number of character which we want to read. 

file.read(4)    # read the next 4 data 

Reading data by traversing and readline()

file = open("abc.text", "r")
print(file.readline())
#we can also print data by looping in file object
for d in file:
   print(d)
