# TODO: Loop through all 50 states, making a question for each. 因为这个程序会随机排序问题和答案,你需要导入random模块➊ 来使用它的函数。capitals变量➋ 包含一个字典,以美国各州为键,以它们的首都为值。由于您想要创建 35 个测验,实际生成测验和答案文件的代码(现在用TODO注释标记)将进入一个for循环...
>>>calcFilePath ='C:\\Windows\\System32\\calc.exe'>>>os.path.split(calcFilePath) ('C:\\Windows\\System32','calc.exe') 注意,您可以通过调用os.path.dirname()和os.path.basename()并将它们的返回值放在一个元组中来创建相同的元组: >>>(os.path.dirname(calcFilePath), os.path.basename(ca...
