pythonifand_Python之if语句及条件语句其实各个语⾔的基础都是相通的。
words = ['soften', 'civilize', 'personalization', 'bakery', strain', 'glimp', 'royals']
for word in words:
if word == 'civilize':
print(word.upper()) #全部⼤写输出
el:
print(word.title()) #⾸字母⼤写输出
result:
Soften
CIVILIZE
Personalization
Bakery有焦虑症怎么办
Strain
Glimp
Royals
*
条件语句包括：！=\<=\>=\>\
chl = 21
凌晨三点fsy = 32
chl >=20 and fsy <=31 #检查两个条件语句，使⽤关键词and result:Fal
(chl >=20) and (fsy <=31) #也可将每个测试放在⼀对括号内
chl >=20 or fay <=31 #使⽤or result:True
*
word = ['bride', 'castle', 'masterpieces', 'mystery', 'tragedy', 'bakery', 'strain', 'glimp']
'castle' in word #使⽤关键词in让python检查列表中是否有'castle'动态路由配置
words = ['emperor', 'castle', 'royal', 'diplomat', 'bakery', 'strain', 'glimp']
日常周记
chl = 'emperors'
if chl not in words: #if not in
print("The word is not in words list!")

age = 12
if age <= 4:
print("I like desrt and trade!")
elif age <= 18: #python这点不⼀样哈，有个elif，可以有若⼲个elif语句
print("I like diplomat and dumpling!")
el:
print("I like nobility and sketch!")
result:

age = 12
if age <= 4:
price = 0
elif age <= 18:
price = 10
el:
price = 20
print("You admission cost is $ " + str(price) +"!") #price要str函数告诉python输出字符**当其中⼀个if语句通过测试，python会跳过其他的if语句测试。
eg：寻找两个列表共同的元素(交集)
chls = ['emperor', 'nobility', 'bakery', 'sauce', 'royal']
fsys = ['emperor', 'Spring Festival', 'approaching', 'nobility']
for chl in chls:
if chl in fsys:
print("We can discover " + chl +"!")
el:
print("Oh my god! The Spring Festival is approaching, prepare " + chl + "!")
result:
We can discover emperor!
内容拼音Oh my god! The Spring Festival is approaching, prepare nobility!
Oh my god! The Spring Festival is approaching, prepare bakery!
Oh my god! The Spring Festival is approaching, prepare sauce!
Oh my god! The Spring Festival is approaching, prepare royal!
