• Read the content line by line of the file f2 and assign it to cont.
• Access each element from 0 to length of cont.
• Check if i is not divisible by 2 then write the content in f1 else pass.

Python Program To Copy Odd Lines Of One File To Other

# open first file in read mode 
f1= open('fileone.txt', 'r') 

open the second file in write mode 
f2= open('filetwo.txt', 'w') 

# read the content of the file line by line 
cont = f1.readlines() 
type(cont) 
for i in range(0, len(cont)): 
 if(i % 2 ! = 0): 
 f2.write(cont[i]) 
 else: 
 pass

# close the second file 
f2.close() 

# open the second file in read mode 
f2= open('filetwo.txt', 'r') 

# read the content of the file 
cont1 = f2.read() 

# print the content of the file 
print(cont1) 

# close all files 
f1.close() 
f2.close()
