Python学习杂记_10_三元运算符

常用三元运算符来简化分支和循环的代码:

 

分支简化:

a = 1
b = 2
c = a if a > 1 else b
print(c)
# 以上几行等同于
a = 1
b = 2
if a >1:
c = a
else:
c = b
print(c)

 

循环简化:

nums = list(range(1,11))
s = [i for i in nums if i % 2 == 0]
print(s)

# 以上代码等同于

s = []
nums = list(range(1,11))
for i in nums:
if i % 2 == 0:
s.append(i)
print(s)
