Introduction

The task is to append the text of one file to another file.

Program

# Open files in read mode and print its content before appending
ipFile1 = open("first.txt", "r") 
print("Content of first file: ", ipFile1.read()) 
ipFile2 = open("second.txt", "r") 
print("Content of second file: ", ipFile2.read())  
ipFile1.close() 
ipFile2.close() 


#Open first file in read mode and second file in append mode
ipFile1 = open("first.txt", "r") 
ipFile2 = open("second.txt", "a+") 
#Append text of first file to second file
ipFile2.write(ipFile1.read()) 

ipFile1.seek(0) 
ipFile2.seek(0) 
#Print both files after appending
print("Content of second file: ", ipFile2.read()) 
#Close the files
ipFile1.close() 
ipFile2.close()

Output

Content of second file after append:-

Explanation

Approach:

• Open both the files in read mode and print the content of files.
• Again open both the files, this time first file in read mode and second file in append mode. This is because we are appending the content of first file to that of second file.
• Append the content using write statement and move the cursor position to beginning using seek() method.
• Print the content of second file after appending.
• Close the files.
