Variable’s case-sensitive Python is a case-sensitive language. If we define a variable with names a = 100 and A =200 then, Python differentiates between a and A. These variables are treated as two different variables (or objects). Example a = 100 A = 200 # value of a print(a) #...

You can reuse variable names by simply assigning a new value to them : >>> x = 100 >>> print(x) 100 >>> x = "Python" >>> print(x) Python >>> Other ways to define value Python allows formatting of large numbers and decimal values for better readability. ...
def 是定义函数的关键词(英文 define 的前三个字母)。当 Python 解释器看到了这个关键词,就知道此处开始定义函数了。 function_name 是函数的名称。按照 PEP 的要求,函数名称的命名方式与变量的命名方式和格式一样。 函数名称之后紧跟着 ([parameters]) ,函数名称和圆括号之间不能有空格,圆括号也不能省略。圆...
DefineVariable(定义变量) section 为变量赋予初始值 AssignValue(为变量赋予初始值) section 使用变量 UseVariable(使用变量) 希望本文对刚入行的小白能够有所帮助,使其能够理解和掌握在Python中初始化变量的方法和技巧。通过不断的实践和学习,相信他能够成为一名优秀的开发者。
Note: Python is atype-inferredlanguage, so you don't have to explicitly define the variable type. It automatically knows thatprogramiz.prois a string and declares thesite_namevariable as a string. Changing the Value of a Variable in Python ...
Variable f is again declared in function and assumeslocalscope. It is assigned value “I am learning Python.” which is printed out as an output. This variable is different from the global variable “f” define earlier Once the function call is over, the local variable f is destroyed. At...
def是定义函数的关键词,这个简写来自英文单词define 函数名后面是圆括号,括号里面,可以有参数列表,也可以没有参数 千万不要忘记了括号后面的冒号 函数体(语句块),相对于def缩进,按照python习惯,缩进四个空格 函数命名 Python对命名的一般要求: 文件名:全小写,可使用下划线 ...
