>>>type(a)<type'int'> Python是一门动态类型语言,和C、JAVA等语言不同,你无需手动指明变量的数据类型,根据赋值的不同你可以随意更改一个变量的数据类型,举例来说刚才我们把“整数”这个数据类型赋值给了a这个变量,现在我们再次赋值一个内容为test的"字符串"(String)数据类型给变量a,然后用type()函数来确认,...
We’re not changing the underlying string that was assigned to it before. We’re assigning a whole new string with different content. In this case, it was pretty easy to find the index to change as there are few characters in the string.How are we supposed to know which character to ch...
Determining Python Variable's TypeTo determine the type of a variable, you can simply use either type() or isinstance() methods, both methods are built-in methods of the Python standard library. In this tutorial, we will be learning about these methods, and how can we use these methods ...

2. Use type() to get Python Variable Type The Pythontype()is abuilt-in functionthat finds the data type of a variable. It takes a variable as an argument and returns the type of the variable. This function is useful when you want to check thedata typeof a variable or perform certain...
如果你需要某个Python函数或语句的快速信息帮助,那么你可以使用内建的help功能。尤其在 你使用带提示符的命令行的时候,它十分有用。比如,运行help(str)——这会显示str类的帮 助。str类用于保存你的程序使用的各种文本(字符串)。按q退出帮助。 Python2和python3 版本不
You can also use the isinstance() function to check if a variable is an instance of a particular type. For example:x = 5 print(isinstance(x, int)) # Output: True print(isinstance(x, str)) # Output: False y = 'hello' print(isinstance(y, str)) # Output: True print(isinstance(y,...
You can get the data type of any object by using the type() function:ExampleGet your own Python Server Print the data type of the variable x: x = 5 print(type(x)) Try it Yourself » Setting the Data TypeIn Python, the data type is set when you assign a value to a variable:...
Note that in Python,variables don't care about the type of an object. Ouramountvariable currently points to an integer: >>>amount=7>>>amount7 But there's nothing stopping us from pointing it to a string instead: >>>amount="hello">>>amount'hello' ...
