Program

Troubleshooting help! The program is supposed to replace the letters input by the user with those in encrypt() but it only comes out empty

def encrypt():

plain = "abcdefghijklmnopqrstuvwxyz?!$&@01234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ"

encrypt="qwertyuioplkjhgfdsazxcvbnm.10987654321QWERTYUIOPLKJHGFDSAZXCVBNM?!$&@"

newEncrypt=""

password= input("Please enter your password: ")

for i in range(0,len(password)):

for j in range(0,len(plain)):

if password[i]==plain[i]:

newEncrypt+= encrypt[j]

break

print(password + "is now: " + newEncrypt)

encrypt()
