Before we start converting between types, it's crucial to understand what floats and integers are. In Python, an integer (int) is a number without a decimal point. A floating-point number (float), on the other
You can also use type conversion such as converting floats to integers during calculations: float_number = 7.85 # Using integer division integer_number = int(float_number // 1) print(integer_number) # Output: 7 # Using multiplication and division integer_number = int(float_number * 1) print...
False otherwise. A string is alphabetic if all characters in the string are alphabetic and there is at least one character in the string. """ pass def isascii(self, *args, **kwargs): # real signature unknown """ Return True if all characters...
浮点型(float) 布尔型(bool) 复数性(complex) 字符型(string):表示数据组成是字符 列表(list):用来表示一组有序元素,后期数据可以修改 ['A','B','C'] 元组(tuple):用来表示一组有序元素,后期数据不可修改 ('A','B','C','1') 集合(set):一组数据无序不重复元素 set([1,2,3,4]) 字典(dictio...
Converting to Float The`float()`function in Python converts integers and strings to floating-point numbers: ```python print(float(3))# Output: 3.0 print(float("3.14"))# Output: 3.14 ``` Just like with`int()`,trying to convert a non-numeric string to a float will cause a`ValueError...
conversion] [":" format_spec] "}" As shown here, f-strings have up to four components. The interpretation is mostly the same as with the .format() method. However, in an f-string, the f_expression component can hold a variable or expression. The equal sign (=) is optional and al...

整型(int)-通常被称为是整型或整数,是正或负整数,不带小数点。 长整型(long integers)-无限大小的整数,整数最后是一个大写或者小写的L 浮点型(floadting point real values)-浮点型由整数部分与小数部分组成,也可以使用科学计数法表示 复数(complex numbers)-复数的虚部以字母J或j结尾。如2+3i...
Comparing floating-point numbers is a bit more complicated than comparing integers. The value stored in a float object may not be precisely what you’d think it would be. For that reason, it’s bad practice to compare floating-point values for exact equality using the == operator. Consider...
