Copy odd lines of one file to another file in Python
Copy odd lines of one file to another file in Python
In this example, we will see a Python program through which we can copy the odd lines of a file to another file.
Suppose we have a file with name "file1.txt" which has the following content in it:
This is line 1 of the file.
This is line 2 of the file.
This is line 3 of the file.
This is line 4 of the file.
This is line 5 of the file.
And we are going to copy the odd lines of “text1.txt” to another file named “text2.txt”.
Program:
# opening the file
file1 = open('file1.txt', 'r')
# creating another file to store odd lines
file2 = open('file2.txt', 'w')
# reading content of the files
# and writing odd lines to another file
lines = file1.readlines()
type(lines)
for i in range(0, len(lines)):
if(i % 2 != 0):
file2.write(lines[i])
# closing the files
file1.close()
file2.close()
# opening the files and printing their content
file1 = open('file1.txt', 'r')
file2 = open('file2.txt', 'r')
# reading and printing the files content
str1 = file1.read()
str2 = file2.read()
print("file1 content...")
print(str1)
print() # to print new line
print("file2 content...")
print(str2)
# closing the files
file1.close()
file2.close()
Output:
file1 content...
This is line 1 of the file.
This is line 2 of the file.
This is line 3 of the file.
This is line 4 of the file.
This is line 5 of the file.
file2 content...
This is line 2 of the file.
This is line 4 of the file.
file1 content...
This is line 1 of the file.
This is line 2 of the file.
This is line 3 of the file.
This is line 4 of the file.
This is line 5 of the file.
file2 content...
This is line 2 of the file.
This is line 4 of the file.
