Python编程快速上手实践项目题目,欢迎指证与优化!
代码:

#! python3
# pw.py - An insecure password locker program.
PASSWORDS = {'email': 'F7minlBDDuvMJuxESSKHFhTxFtjVB6',
'blog': 'VmALvQyKAxiVH5G8v01if1MLZF3sdt',
'luggage': '12345'}
import sys
import pyperclip
if len(sys.argv) < 2:
print('Usage: python pw.py [account] - copy account password')
sys.exit()

account = sys.argv[1]
#sys.argv[]是用来获取命令行参数的,sys.argv[0]表示代码本身文件路径,所以参数从1开始
# first command line arg is the account name
print (account)

if account in PASSWORDS:
pyperclip.copy(PASSWORDS[account])
print('Password for ' + account + ' copied to clipboard.')
else:
print('There is no account named ' + account)

#测试命令:打开CMD,输入py.exe + 文件名(绝对路径)+ 命令内容,
#比如:py.exe D:\python_work\口令保管箱.py email

执行结果:

email
Password for email copied to clipboard.
