分支选择结构
if 2 > 1:
print('2 > 1 is true')
else:
print('2 > 1 is false')
if 1 == 1:
print('1 == 1 is true')
多分支选择结构
color = input()
if color == 'red':
print('color is red')
elif color == 'green':
print('color is green')
elif color == 'blue':
print('color is ')
else:
print('color is other')
分支嵌套结构
sex = input()
age = int(input())
if sex == 'male':
if age > 50:
print('old male')
else:
print('young male')
else:
if age > 50:
print('old female')
else:
print('young female')
