前言:
此刻兄弟们对“python有等级吗”可能比较看重,同学们都想要学习一些“python有等级吗”的相关文章。那么小编同时在网络上收集了一些关于“python有等级吗””的相关资讯,希望姐妹们能喜欢,你们快快来了解一下吧!第 1 级:基本功能:
pythondef greet(name): return f“Hello, {name}!”**级别 2:带参数和返回的函数:
def add(a, b): return a + b级别 3:默认参数值:
def power(base, exponent=2): return base ** exponent**级别 4:参数的可变数量:
def sum_all(*args): return sum(args)**级别 5:关键字参数:
def person_info(**kwargs): return kwargs.get(“name”, “Unknown”), kwargs.get(“age”, “Unknown”)'**级别 6:Lambda 函数:
double = lambda x: x * 2'''第 7 级:递归函数:
def factorial(n): if n == 0: return 1 return n * factorial(n — 1)第 8 级:高阶函数:
pythondef apply_operation(func, x, y): return func(x, y)reslut= apply_operation(add, 3, 4)**级别 9: 装饰器:
def uppercase_decorator(func): def wrapper(*args, **kwargs): result = func(*args, **kwargs) return result.upper()return wrapper@uppercase_decoratordef greet(name):return f”Hello, {name}!”greet(“Alice”)丝”)**级别 10:生成器:**
def countdown(n): while n > 0: yield nn -= 1**级别 11:用于映射的匿名函数 (Lambda):
numbers = [1, 2, 3, 4, 5]squared = list(map(lambda x: x ** 2, numbers))**级别 12:列表推导
squared = [x ** 2 for x in numbers]**级别 13:生成器表达式:
squared_gen = (x ** 2 for x in numbers)**级别 14:部分函数:
from functools import partialdef power(base, exponent): return base ** exponentsquare = partial(power, exponent=2)cube = partial(power, exponent=3)**级别 15:闭包:**
def outer_function(x): def inner_function(y): return x + yreturn inner_functionadd_five = outer_function(5) result = add_five(3)
