python if else 操作(笔记)

nightowlxjy

1、基础写法
其实python的锁进就类似于java括号里面的内容
print("if else 操作")

temperature = 15

if temperature > 30:
    print("It's warm")
    print("drink water")
elif temperature > 20:
    print("It's nice")
else:
    print("It's cold")
print("done")

2、三元表达式
if else的简略写法 --> 演变python三元表达式
age = 22
if age >= 18:
    print("Eligible")
else:
    print("No eligible")

age = 22
if age >= 18:
    mesage = "Eligible"
else:
    mesage = "No eligible"
print(mesage)


age = 22
# python 三元表达式 为真的结果 if 表达式 else 为假的结果
mesage = "Eligible" if age >= 18 else "No eligible"
print(mesage)
3、多条件表达式写法
包含或 且 非
hight_income = True
good_credit = True
student = False

if hight_income and good_credit:
    print("Eligible")
else:
    print("No Eligible")

if not student:
    print("Eligible")
else:
    print("No Eligible")

if (hight_income or good_credit) and not student:
    print("Eligible")
else:
    print("No Eligible")
