Working in Read Mode

File Handling: Read Mode...

There is a file called read_mode_file.txt that have the contents of: read_mode_file.txt

Hi,
My name is: read_mode_file.txt
I am created before the creation of the py file.

Example 1:

The open command will open the py file in the read mode and the for loop will print each line present in the file

import os
# The file "read_mode_file.txt", will be opened with the reading mode
file = open('read_mode_file.txt', 'r')

# Printing each line one by one in the file
for each in file:
    print(each)

Example 2:

We will extract a string that contains all characters in the python file then we can use file.read()

file = open("read_mode_file.txt", "r")
print(file.read())

Example 3: We can read a file using the with statement

with open("read_mode_file.txt") as file:
    data = file.read()

print(data)

Example 4: We can call the certain number of characters from the file

file = open("read_mode_file.txt", "r")
print (file.read(5))

Output of all the examples:
