File Handling in Python

File Handling in Python

Modes

Read Mode 'r'

Write Mode 'w'

Append(Editable) 'a'

to read binary file 'rb'

To delete a file use remove()

To open a source file in readmode

Eg;

with open('source.txt','r') as file:


print(file,type(file))

To get to know the type of the file

with open('source.txt','r') as file:

print(file,type(file))

To create a new file or over-write use Write mode

Eg:

with open('source1.txt','w') as file:

file.write('e f g h')

file.write('i j k l')

To append more info we use append mode

Eg:

with open('source1.txt','a') as file:

file.write('m n o p')

saved file will be

e f g hi j k lm n o p

To check whether file present or not

import os

if os.path.isfile('source1.txt'):

print('source1 founded')

else:

print('source1 not founded')

o/p:

source1 founded

Again to read the content of that file

with open('source1.txt','r') as source_file:

content=source_file.readline()

print(content)

o/p

e f g hi j k lm n o p

To read binary file 'rb'

with open('binary.txt','rb') as source_file:

To delete a file

import os

os.remove('source1.txt')
