一、If语句
- 需要注意的是:在Python中If语句或循环语句是没有用大括号括起来的,所以编写程序时一定要严格按照编写格式来,什么时候要Tab空格一定不能忘记!!!
- If条件语句那一行,最后记得加冒号:
If条件语句格式:
if condition 1:
statement 1
elif condition 2:
statement 2
else:
statement 3
Practise 1:
# If statement
x = 4
if x < 1:
score = "low"
elif x <= 4:
score = "medium"
else:
score = "high"
print (score)
输出结果:
medium
Practise 2:
# If statment with a boolean
x = True
if x:
print ("it worked")
输出结果:
it worked
