format函數(shù)用法python
在Python中，format()函數(shù)是一個(gè)非常實(shí)用的字符串格式化工具，它可以將指定的值插入到字符串的占位符位置，從而生成一個(gè)新的字符串。format()函數(shù)的基本語法如下：
成都創(chuàng)新互聯(lián)公司是一家以重慶網(wǎng)站建設(shè)公司、網(wǎng)頁設(shè)計(jì)、品牌設(shè)計(jì)、軟件運(yùn)維、seo優(yōu)化、小程序App開發(fā)等移動(dòng)開發(fā)為一體互聯(lián)網(wǎng)公司。已累計(jì)為紗窗等眾行業(yè)中小客戶提供優(yōu)質(zhì)的互聯(lián)網(wǎng)建站和軟件開發(fā)服務(wù)。
str.format(*args, **kwargs)
*args表示可變數(shù)量的位置參數(shù)，**kwargs表示可變數(shù)量的關(guān)鍵字參數(shù)，這些參數(shù)將被插入到字符串中的占位符位置。
下面是一些使用format()函數(shù)的示例：
1、基本用法
name = "張三"
age = 25
result = "我的名字是{}，我{}歲了。".format(name, age)
print(result) # 輸出：我的名字是張三，我25歲了。
2、使用索引和關(guān)鍵字參數(shù)
result = "我的名字是{0}，我{1}歲了。".format(name, age)
print(result) # 輸出：我的名字是張三，我25歲了。
3、使用關(guān)鍵字參數(shù)
result = "我的名字是{name}，我{age}歲了。".format(name=name, age=age)
print(result) # 輸出：我的名字是張三，我25歲了。
4、格式化數(shù)字和貨幣
pi = 3.1415926
result = "圓周率的值約為{:.2f}。".format(pi)
print(result) # 輸出：圓周率的值約為3.14。
money = 123456789.987654321
result = "金額為：{:,.2f}".format(money)
print(result) # 輸出：金額為：1,234,567,899.88
5、對(duì)齊字符串
name = "張三"
age = 25
result = "{:<10}{:>5}".format(name, age)
print(result) # 輸出：張三 25
6、重復(fù)字符串
result = "{:*<10}".format("Hello")
print(result) # 輸出：HelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHilloHallloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeloHeroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroHerroloorooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooododdooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddooddodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoodoododddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddoccccccccccccccccccccccccccccccccccccccccccccccccccccccccccoocococococococococococococococococococococococococococococococococococococococococccceeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffgggggggggggggggggggggggggggggggggggggggggggggggyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyoouuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuurrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrruunnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnoppppppppppppppppppppppppppppppppppppoqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqopmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmooopppoppoppoppoppoppopoppoppoppoppoppopopp" * 100)
