All floating-point numbers must have a decimal part, which can be 0, which is designed to distinguish floating-point numbers from integer types. There are two kinds of decimal representation and scientific notation. Scientific numeration uses the letter e or E as a symbol for a power, with ...

If you need to print an integer number beyond the 4300-digit limit, then you can use the sys.set_int_max_str_digits() function to increase the limit and make your code work.When you’re working with long integers, you can use the underscore character to make the literals more readable...
浮点字面值给予float类型实际提供的精度更高。Python会尽最大努力将这样的字面值Map到接近您想要的值。
