1. int(): converts to an integer my_string = "123" my_number = int(my_string) print(my_number) Output: 123 2. float(): converts to a floating-point number my_string = "3.14" my_number = float(my_string) print(my_number) Output: 3.14 3. complex(): converts to a complex n...
这时可以使用try...except语句来捕获异常并进行处理。 # 示例:处理转换异常defconvert_to_number(s):try:returnint(s)exceptValueError:print(f"无法将 '{s}' 转换为数字")returnNone# 测试print(convert_to_number("abc"))# 输出: 无法将 'abc' 转换为数字 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. ...
defconvert_to_float(string):ifis_number(string):returnfloat(string)else:raiseValueError("The input string cannot be converted to a float.") 1. 2. 3. 4. 5. 这段代码定义了一个convert_to_float()函数,它接受一个字符串作为参数,并返回一个浮点数类型的结果。在函数内部,我们同样调用is_number()...

Convert a number or string to an integer, or return 0 if no arguments are given. If x is a number, return x.__int__(). For floating point numbers, this truncates towards zero. If x is not a number or if base is given, then x must be a string, ...

The string can contain additional characters after those that form the integral number, which are ignored and have no effect on the behavior of this function. If the first sequence of non-whitespace characters in str is not a valid integral number, or if no such sequence exists because either...
