我知道您可以在Python GUI中打开文件,浏览器和URL。但是,我不知道如何将其应用于程序。例如,以下都不起作用。 (以下是我不断增长的聊天机器人程序的片段):
def browser():
print('OPENING FIREFOX...')
handle = webbroswer.get() # webbrowser is imported at the top of the file
handle.open('http://youtube.com')
handle.open_new_tab('http://google.com')
和
def file():
file = str(input('ENTER THE FILE\'S NAME AND EXTENSION:'))
action = open(file, 'r')
actionTwo = action.read()
print (actionTwo)
就上述顺序而言,这些错误发生在个别运行中:
OPENING FIREFOX...

我处理这个错误,还是我不能在程序中使用open()和webbrowser?
答案 0 :(得分:6)
你应该阅读错误并尝试理解它们 - 在这种情况下它们非常有用 - 因为它们通常是:
第一个说NameError: global name 'webbroswer' is not defined
。
您可以在此处看到代码中webbrowser
拼写错误。它还告诉你它找到错误的行(第38行)
第二个IOError: [Errno 2] No such file or directory: 'file.txt'
告诉您正在尝试打开不存在的文件。这不起作用,因为您指定了
action = open(file, 'r')
表示您正在尝试读取文件。 Python不允许从不存在的文件中读取。
