Given two text files, the task is to write a Python program to copy contents of the first file into the second file.
The text files which are going to be used are second.txt and first.txt:
Method #1: Using File handling to read and append
We will open first.txt in ‘r’ mode and will read the contents of first.txt. After that, we will open second.txt in ‘a’ mode and will append the content of first.txt into second.txt.
Example:
Python3
# open both fileswith open('first.txt','r') as firstfile, open('second.txt','a') as secondfile: # read content from first file for line in firstfile: # append content to second file secondfile.write(line) |
Output:
Method #2: Using File handling to read and write
We will open first.txt in ‘r’ mode and will read the contents of first.txt. After that, we will open second.txt in ‘w’ mode and will write the content of first.txt into second.txt.
Example:
Python3
# open both fileswith open('first.txt','r') as firstfile, open('second.txt','w') as secondfile: # read content from first file for line in firstfile: # write content to second file secondfile.write(line) |
Output:
Method #3: Using shutil.copy() module
The shutil.copy() method in Python is used to copy the content of the source file to destination file or directory.
Example:
Python3
# import moduleimport shutil # use copyfile()shutil.copyfile('first.txt','second.txt') |
Output:
