Defining Python functions: Syntax and naming rulesIn Python, you can define a function using the "def" keyword followed by the function name, parentheses containing optional parameters, and a colon. Function bodies, which contain the code to be executed when the function is called, are indented...
foo=long_function_name(var_one,var_two,var_three,var_four)# 错误:# 在不使用垂直对齐时,禁止在第一行放置参数 foo=long_function_name(var_one,var_two,var_three,var_four)# 由于缩进不可区分,需要进一步的缩进 deflong_function_name(var_one,var_two,var_three,var_four):print(var_one) 4个空...
Defining a Function in Python While defining a function in Python, we need to follow the below set of rules: The def keyword is used to start the function definition. The def keyword is followed by a function name and parentheses containing the arguments passed by the user and a colon at...

function_name - 函数名,起名最好有意义。 arg1 - 位置参数 ,这些参数在调用函数 (call function) 时位置要固定。 arg2 = v - 默认参数 = 默认值,调用函数的时候,默认参数已经有值,就不用再传值了。 *args - 可变参数,可以是从零个到任意个,自动组装成元组。 **kw - 关键字参数,可以是从零个到任意...

The concept of scope rules how variables and names are looked up in your code. It determines the visibility of a variable within the code. The scope of a name or variable depends on the place in your code where you create that variable. The Python scope concept is generally presented ...

Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although ...
