python-格式化输出

格式化输入方式一

 %：占位符

s：string，字符串

d：digit，数字

%%：显示单纯的%

print("我叫%s，今年%岁，身高%s。"%(name,age,height)) 

msg = "我叫%s，今年%岁，身高%s。"%(name,age,height)
print(msg)

注意：如果print的内容中包含%号：

msg = "我叫%s，今年%岁，身高%s，学习进度为3%%。"%(name,age,height)   #前一个%表示转义字符
print(msg) 

格式化输入方式二

name ='A'
sex='man'
age=18
msg = F'姓名：{nanme}，性别：{sex}，年龄：{age}'  #小写f也可以
print(msg)

print(f'{4-3'}

name='A'
print(f'{name.lower()}')


ar={'name':'A','age':11}
msg = f'name is {ar['name']},age is {ar['age']}'
print(msg)


#多行f
speaker = f'Hi {name}.'\
              f'You are {age} years old.'\
               f'You are a {ajd} guy!'
print(spearker)

#使用lambda表达式
x=5
print(f'{(lambda x: x*2) (x)}')
