length len() 长度 parameter param 参数 return 返回 define 定义 def function 功能,函数 require 必须 miss 丢失 object 对象、事物 callable 可调用 default 默认的 follow 跟在…后面 global 全球,全局的 slice 切 remove 移除 list 列表 dict 字典 key
函数的定义基本结构如下：def function_name(parameters): """docstring""" statement(s) ...
In the following code, we define a variable port that stores an integer and banner that stores a string. To combine the two variables together into one string, we must explicitly cast the port as a string using the str() function. >>> port = 21 >>> banner = “FreeFloat FTP Server...
print ("We found %(error_count)d errors" % self.__dict__) # 等同于 print ("We found %d errors" % self.error_count) 另外,我们还可以用如下的方式,对字符串格式化进一步的控制:%[(name)][flags][width].[precision]typecode,其中: (name)为命名 flags可以有+,-,’ ‘或0。+表示右对齐。-...

It’s possible to define functions inside other functions. Such functions are called inner functions. Here’s an example of a function with two inner functions:Python inner_functions.py def parent(): print("Printing from parent()") def first_child(): print("Printing from first_child()")...
Local (or function) scope is the code block or body of any Python function or lambda expression. This Python scope contains the names that you define inside the function. These names will only be visible from the code of the function. It’s created at function call, not at function ...
