Python if语句

if语句简单使用

names=['Yang','Liu','Qian','Zhang','Zhai']
for name in names:
	if name=='Zhang':
		print(name.upper())
	else:
		print(name.lower())

输出结果

yang
liu
qian
ZHANG
zhai

• 检测特定值是否包含在列表中

names=['Yang','Liu','Qian','Zhang','Zhai']
name='Xiao'
if name not in names:
	print(name+", welcome!"）

输出结果

Xiao, welcome!

• 多个elif代码块的使用

point=95

if point>95:
	print("The Best!")
elif point>80:
	print("Good!")
elif point>60:
	print("Pass!")
else:
	print("NOPASS!!!")

输出结果

Good!
