Answer 1

import os
name = input("Name :")
roll = input("Roll No :")
branch = input("Branch :")

add ="name :" + name + "\n" +"Roll No :" + roll +"\n" +"Branch :"+branch

f = open(name + ".txt","a+") # This is where you are opening the file

# Below line is not contributing to the posted code at all
# m = os.path.join(name +".txt")

f.write(add)
f.close()
