Python local variable 'Current_Balance' referenced before assignment
我不知道为什么会这样。想修一段时间了
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | def Bettings(): while True: if"Rolling in 35." in Label.text: Updated_Balance = driver.find_element_by_xpath("""//*[@id="balance"]""") if"Rolling in 23." in Label.text: Current_Balance = driver.find_element_by_xpath("""//*[@id="balance"]""") if"Rolling in 28." in Label.text: if Current_Balance < Updated_Balance: GrayBetButton.click() if Current_Balance > Updated_Balance: RedBetButton.click() Bettings() |
错误:
1 | UnboundLocalError: local variable 'Current_Balance' referenced before assignm |
只有在通过
当您直接通过
您可能希望在顶部创建此变量,如下所示:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | def Bettings(): current_balance = 0 while True: if"Rolling in 35." in Label.text: updated_balance = driver.find_element_by_xpath("""//*[@id="balance"]""") if"Rolling in 23." in Label.text: current_balance = driver.find_element_by_xpath("""//*[@id="balance"]""") if"Rolling in 28." in Label.text: if current_balance < updated_balance: grayBetButton.click() if current_Balance > updated_balance: redBetButton.click() Bettings() |
注意,按照惯例,变量名往往以非大写字母开头(类名最好是大写)。
