python - 写入文本文档时，它不会给出所有给定的密码

Question

我制作了一个密码生成器，它按请求的数量和长度为我提供密码，我想将所有给定的密码保存到名为“Your_Saved_Keys”的 txt 文档中，但是仅保存生成的密码之一，而不是全部他们

import random
import time

print('''
Password Generator V2.0
=======================
''')

chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@£$%^&*().,? 
0123456789'

number = input('number of passwords? ')
number = int(number)

length = input('password length? ')
length = int(length)

print('''\nhere are your passwords: ''')

for pwd in range(number):
  password = ''''''
  for c in range(length):
    password += random.choice(chars)
  print(password)

save = input("""Do you want to save it to a txt file? Y/N""")

if save == "Y":
  format = ".txt"
  title = "Your_Saved_Keys"
  text_file = open(title + format, "w")
  text_file.write(password))
  print("Save Successful")

if save == "N":
  print("You Selected No")
print("-----------------------------------")
input("Press enter to exit")

您的密码变量每次都会被覆盖。其中只有最后一个密码可用。您可以将所有密码保存到列表中，然后将其写入文件。此代码正在运行

import random
import time

print('''
Password Generator V2.0
=======================
''')

chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@£$%^&*().,?0123456789'

number = input('number of passwords? ')
number = int(number)

length = input('password length? ')
length = int(length)

passwords=[]
print('''\nhere are your passwords: ''')

for pwd in range(number):
  password=""
  for c in range(length):
      password+=random.choice(chars)
  passwords.append(password)
  print(password)

save = input("""Do you want to save it to a txt file? Y/N""")

if save == "Y":
  format = ".txt"
  title = "Your_Saved_Keys"
  with open(title + format, "w") as text_file:
      for password in passwords:
          text_file.write(password+'\n')
  print("Save Successful")

if save == "N":
  print("You Selected No")
print("-----------------------------------")
input("Press enter to exit")
