keyboard - pywinauto.keyboard.KeySequenceError: `}` 前面应该有 `{`

问题描述

有以下代码，它将生成的密码输出到命令行（使用打印命令）但是当我将生成的密码发送到密码文本框时，我得到了错误

pywinauto.keyboard.KeySequenceError:}应该在前面{

app = Application(backend="uia").connect(title = "SKF Insight Rail Manager")

app.top_window().set_focus()

password = random.choice(string.ascii_lowercase)
password += random.choice(string.punctuation)
password += random.choice(string.ascii_uppercase)
password += random.choice(string.digits)
for i in range(4):
    randomSource = string.ascii_letters + string.digits + string.punctuation
    password += random.choice(randomSource)

解决方案

花括号是一种转义序列。您需要通过用{}. 在您的情况下，它应该看起来像这样：

password = "{}}" # wrap by {} for send_keys
password += "{{}" # wrap by {} for send_keys
password += random.choice(string.digits)
password += random.choice(string.punctuation)
for i in range(4):
    randomSource = string.ascii_letters + string.digits + string.punctuation
    password += random.choice(randomSource)

# tricky replace is needed for human readable form of password
print("Generated password:" + password.replace('{}}', '}').replace('{{}', '{'))

time.sleep(1)

keyboard.send_keys(password)
