我把学习python过程中所用到的实例进行了简单的总结，内容很简单可以自己复制到电脑上跑一下，希望能对初学python的同学有一些帮助，后续也会更新更多的内容

实例一文字处理

name = input('what is your name? ')
favorite_color = input('what is your favorite color?')
print('Hi ' + name)
print(name +' like '+ favorite_color)birth_year = input('birth year')
age = 2020 - int(birth_year)
print(age)

实例二文字处理+运算

ciurse = "'python'a good language"
print(ciurse[-1])
print(ciurse[0:3])
print(ciurse[2:])
print(ciurse[:-1])
first = 'jone'
last = 'smith'
message = first + '['+last+'] is a code'
msg = f'{first} [{last}] is a coder'
print(message)
print(msg)
print(len(ciurse))
print(ciurse.upper())
print(ciurse.lower())
print(ciurse.find('o'))
print(ciurse.replace('good','great'))
print('good' in ciurse)
print(10 + 3)
print(10 / 3)
print(10 % 3)
print(10 ** 3)
x = 10
x += 3
print(x)#数学就是解题
y = 2.9
print(round(y))
print(abs(-2.9))
print(math.floor(-2.9))#math说明
print(math.floor(2.9))

实例三判断语句

is_hot = False
is_cold = True
if is_hot:print("It is a hot day")
elif is_cold:print("It is a cold day")
else:print("It is a cold day")print("Enjoy your day")
price = 100000
has_good_credit = True
if has_good_credit:down_payment = price*0.1
else:down_payment = priceprint(down_payment)has_good_credit = True
has_high_income = False
if has_good_credit and has_high_income: #or    and notprint('loah')
else:print('NO')tem = 30
if tem > 30:print('It is a hot day')
elif tem == 30:print('It is not a hot day')
else:print('It is a cold day')name = 'J'
if len(name) < 3:print('short')
else:print('long')
