#傳統(tǒng)函數(shù)：
def add(num1):
	return num1 * 2
調(diào)用：add(2)
輸出：4
def add(num1,num2):
	return num1 + num2
調(diào)用：add(1,2)
輸出：3
#匿名函數(shù)：
result = lambda x: x*2
調(diào)用：result(2)
輸出：4 
result = lambda x,y: x+y
調(diào)用：result(x=1,y=2)
輸出：3

3.匿名函數(shù)的幾種使用方式

#1、匿名函數(shù)組合三目運(yùn)算
傳統(tǒng)函數(shù)
def compare(x,y):
	if x > y:
		return x
	else:
		return y
調(diào)用：compare(2,1)
輸出：2
匿名函數(shù)
compare = lambda x,y: x if x > y else y
調(diào)用：compare(2,1)
輸出：2

#2、把lambda作為一個(gè)方法傳入傳統(tǒng)函數(shù)
schools = ["Python基礎(chǔ)",
		   "Python爬蟲(chóng)",
		   "Java編程",
		   "Java Web",
		   "Python數(shù)據(jù)分析"
]
def keyword_serch(keys,func):
	search_result= []
	for result in keys:
		if func(result):
			search_result.append(result)
	return search_result
condition = lambda x: True if "Python" in x else False
調(diào)用：keyword_serch(schools,condition)
輸出： ["Python基礎(chǔ)","Python爬蟲(chóng)","Python數(shù)據(jù)分析"]

#3、如何給def函數(shù)中的lambda傳參數(shù)？
def main():
	return lambda x: True if x == 10 else False
			（如果x等于10返回真，否則為假）
調(diào)用：main()(10) 
	執(zhí)行main函數(shù)，但是main不需要傳參；
	第二個(gè)括弧則是為lambda傳送的x的參數(shù)
輸出：True

#4、把lambda作為一個(gè)方法傳入傳統(tǒng)函數(shù)
def income(basic,transport,phone):
	return lambda x: x+basic+transport+phone
調(diào)用：total = income（1000,2000,3000）
	 total(4000)
輸出：10000
schools = ["Python基礎(chǔ)",
		   "Python爬蟲(chóng)",
		   "Java編程",
		   "Java Web",
		   "Python數(shù)據(jù)分析"
]
def keyword_search(keys,func):
	search_result= []
	for key in keys:
		if func(key):
			search_result.append(key)
	return search_result
def search_condition(c):
	return lambda x: True if c in x else False
python = search_condition("Python")
調(diào)用：keyword_search(schools,python)
輸出：["Python基礎(chǔ)","Python爬蟲(chóng)","Python數(shù)據(jù)分析"]
