def is a keyword that indicates that this is a function definition. The name of the function is print_lyrics. The rules for function names are the same as for variable names: letters, numbers and underscore are legal, but the first character can’t be a number. You can’t use a keywor...
函数(function):一个有名称的语句序列,可以进行某种有用的操作。函数可以接收或者不接收参数,可以返回或不返回结果。 函数定义(function definition):一个用来创建新函数的语句,指定函数的名称、参数以及它包含的语句序列。 函数对象(function object):函数定义所创建的值。函数名可以用作变量来引用一个函数对象。 函数...
max() Function in Python The max() function returns the largest item in an iterable (like a list, or tuple) or among multiple numbers given as arguments. Example 1: Python 1 2 3 4 # Finding the maximum value in a list numbers = [10, 25, 18, 40] print(max(numbers)) Output:...

But they are majorly preferred only on the simple conditions that don’t require any long function definition. Syntax: lambda arguments: value_if_true if condition else value_if_false Example: Python 1 2 3 4 check_even_odd = lambda x: "Even" if x % 2 == 0 else "Odd" print(check...

目前为止,我们只使用了Python自带的函数, 但是创建新函数也是可能的。 一个函数定义(function definition)指定了新函数的名称 以及当函数被调用时执行的语句序列。 下面是一个示例: def print_lyrics(): print("I'm a lumberjack, and I'm okay.") ...

If you want the function to take parameters, you include one or more names inside the parentheses of the function definition. Any value to be returned is given using the ubiquitous “return” keyword: XML 复制 def theKnightsWhoSayNi(gift): if gift == "shrubbery": return ("You must...
