How to Copy File in Python

Python supports copying of source file into the destination file. Here i’ve described few methods to copy file in python.

It is easier than other programming languages and easy to understand for the developer. We have to import some libraries and write a few lines of code.

File Copy in Python

There are 2 Methods to copy the content of source file into the destination file

Method 1: Using Python modules

In this method, we use some python modules and use them for copying source file into the destination file.

Steps

Import python modules shutil and os
Assign destination directory using chdir() function
Use copy() function to copt source file into destination file

Note: Syntax of shutil.copy function is

shutil.copy('Spath' , 'Dpath')

Here Spath = Path of source file

Dpath = Path of the destination file

Example

Suppose we have source file sourcefile.txt in D: drive and we want to copy the content of that file into destination file destfile.txt in D: drive. We have to use the above steps for the copying process.

Code

import shutil,os    # Import two modules shutil and os
os.chdir('D:\')    # Assign directory using chdir() function in which we want to perform copy function
shutil.copy('D:\sourcefile.txt','D:\destfile.txt') #Here first path is for soucefile amd second path is for destinationfile

Method 2: Using write function

In this method, we assign the source file path and destination file path to variables. Then we use them for accessing write function in python.

Steps

Open source file with reading permission and assign it to Spath
Open destination file with write permission and assign it to Dpath
Use write() function to copy content of source file into destination file

Note: We have to close the destination file after copying the content of source file into the destination file. We can use close() function for it.

Example

Code

Spath = open("D:\sourcefile.txt" , "r") # Open Source file and assign it to Spath with read permission
Dpath = open("D:\destfile.txt" , "w")   # Open destination file and assign it to Dpath with write permission
Dpath.write(Spath.read())               # Use write function to copy Spath into Dpath
Dpath.close()                           # Close Dpath file
