在Python中,强制类型转换分为两种,分别是显式转换(Explicit Casting)和隐式转换(Implicit Casting)。显式转换是 programmer 严格指定的数据类型转换,而隐式转换则是计算机自动完成的。我们主要关注显式转换,尤其是在处理自定义类时。 1.1 显式转换 显式转换通常使用Python内置的转换函数进行。这些函数包括:
英文:what is Typecasting: Typecasting is data type conversion. It allows you to specify a data type to a variable, or to convert a variable of one data type into another data type. 函数int() 要将浮点数转换为整数,我们使用Python内置函数int() 例子: number = 5.3251 number_int = int(numbe...
This type of conversion is also called typecasting because the user casts (changes) the data type of the objects. Example 2: Addition of string and integer Using Explicit Conversion num_string ='12'num_integer =23print("Data type of num_string before Type Casting:",type(num_string))# exp...
In explicit type conversion, python uses inbuilt functions which convert a given data type to another required data type. It is also known astype castingbecause we explicitely cast an object from one type to another type using a predefined function such asint(),float(),str(), etc. Let’s u...

You’ll learn more about the modulus of complex numbers later. When you continue deriving the formula, this is what you’ll get:Note that complex numbers don’t support floor division, also known as integer division:Python >>> z1 // z2 Traceback (most recent call last): File "<...
英文:To print a string, you can also use Python's string formatting, or what is called f-strings. f-string 输出字符串举例: print(f'Hello World') #output: Hello World 2.1.1使用 f-string连接变量 如果希望在字符串文本中包含打印变量,只需将变量括在左大括号和右大括号中 ...
