Python如何格式化输出

# 旧格式化输出
print("name is %s,age is %d,my salary is %2.1f k"
      % ('tony', 18, 15.2))

#2.1f为输出的宽度，整数为2个宽度，保留1位小数

#结果
name is tony,age is 18,my salary is 15.2 k

# format方法
#不设置指定位置，按默认顺序
str0 = "名字为{}，年龄为{}"
print(str0.format('li',18))

#设置指定位置
str1 = "名字为{0}，年龄为{1}"
print(str1.format('li', '18'))

str2 = "name is{0},{0} age is {1}"
print(str2.format('li', '18'))

#设置参数
print('网站名:{name}，网址:{url}'.format(name = '博客园',url = 'https://blog.sholdboyedu.com/?p=3250'))


#结合字典
str3 = {"name": "HammerZe博客", "url": "https://blog.sholdboyedu.com/?p=3250"}
print("博客名:{name},博客地址：{url}".format(**str3))

#结合列表

str4 = ["HammerZe博客", "https://blog.sholdboyedu.com/?p=3250"]
print("博客名:{0[0]},博客地址：{0[1]}".format(str4)) #0必须有
