python的条件判断if、elif、else操作是什么样的

#简单的if语句#判断为真执行代码块内容if True:    print("好好学Python!")#因为是False这里不会打印输出if False:    print("这里不会打印")# 一个完整的if elif else# 代码块 lang = 'Python'#lang = 'Java'if lang == 'Python':    print("Hello " + lang)elif lang == 'Java':     print("Hello " + lang)elif lang == 'Go':     print("Hello " + Go)else:    print("No Match!")#使用and or not#进行条件判断# and 操作user = 'yale'login_in = Trueif user == 'yale' and login_in:    print('admin login!')else:    print('common login!')# or 操作user = 'yale'login_in = Trueif user == 'yale' or login_in:    print('admin login!')else:    print('common login!')# not 操作login_in = Falseif not login_in:    print('Please login!')else:    print('login in!')#比较lista = [1,2,3]b = [1,2,3]print(a == b)#Trueprint(a is b)#False#因为在内存中a b是两个不同的对象#两个变量的地址不同print(id(a))print(id(b))#如下情况会为Truea = [1,2,3]b = aprint(id(a))print(id(b))#True#内存中是相同的对象print(a is b)#### Python默认为False的值##### False# None# 0# 任何空的序列或者列表，例如: '',（）,[].# 任何空的mapping,例如:{}condition = Falseif condition:    print('True values')else:    print('False values')
