How to add text using append in python-CodePudding

So I created python password generator. I want the password created to add itself to a txt file but I cant find a way. Heres the code:

  import random
passlen = int(input("enter the length of password "))
s="abcdefghijklmnopqrstuvwxyz01234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()?"
p = "".join(random.sample(s,passlen ))
file = open("pass.txt", "a")
file.write("Password: ")
file.close()
print(p)
file = open("pass.txt", "r")
print("Output of Readlines after appending")
print(file.read())
print()
file.close()

CodePudding user response：

with open("pass.txt", "r") as myfile:
myfile.write(p)

hope this help

CodePudding user response：

You are not writing p into file. Try:

import random

passlen = 10
s = "abcdefghijklmnopqrstuvwxyz01234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()?"

p = ''.join(random.sample(s, passlen))

with open('pass.txt', 'a') as f:
    print(f"password: {p}", file=f)

with open('pass.txt', 'r') as f:
    print("Now the contents of pass.txt:")
    print(f.read())

Note that with open is preferred (to open ... close) in general.
