使用浮点数作为列表索引会导致TypeError,错误信息为“python list indices must be integers or slices, not float”。这是因为Python无法将浮点数转换为有效的列表索引。 提供解决方案或建议,以避免出现“python list indices must be integers or slices, not float”的错误: 确保在访问列表元素时使用整数或切片作为...

否则,Python 会认为你只是在普通括号内输入了一个值。逗号让 Python 知道这是一个元组值。(与其他一些编程语言不同,在 Python 中,在列表或元组的最后一项后面有一个尾随逗号是没有问题的。)在交互式 Shell 中输入下面的type()函数调用,以查看区别: >>> type(('hello',)) <class 'tuple'> >>> type(('...

While loop to identify integer in Python, An input will always be an str by default unless you modified the type with int () or float () in your case. You can use 'try' instead to check for this: while True: x = input ("How many cubic cm of water does the item displace") try...
