多個(gè)if語(yǔ)句和 if…elif…的區(qū)別
- 多個(gè)if語(yǔ)句，程序運(yùn)行時(shí)會(huì)遍歷所有if；
- if-elif颊埃，只要if或后續(xù)某一個(gè)elif之一滿足邏輯值為True制肮，則程序執(zhí)行完對(duì)應(yīng)輸出語(yǔ)句后自動(dòng)結(jié)束該輪if-elif（即不會(huì)再去執(zhí)行后續(xù)的elif或else)
if a>10:
print('a nice')
if a>11:
print('a very nice')
if a>=12:
print('a very very nice')
b=12
if b>10:
print('b nice')
elif b>11:
print('b very nice')
elif b>=12:
print('b very very nice')
輸出結(jié)果：
a nice
a very nice
a very very nice
b nice
a=12
if a>12:
print('a nice')
if a>11:
print('a very nice')
if a>=12:
print('a very very nice')
b=12
if b>12:
print('b nice')
elif b>11:
print('b very nice')
else:
print('b very very nice')
a very nice
a very very nice
b very nice
