python string函式是什麼?一起來看下吧:
python string函式包括:
1、str.capitalize:將原字串內的首字母轉成大寫,其他部分小寫,再返回新字串
print("s.capitalize() = {function}"s.capitalize() = Abcada a
2、str.lower:將原字串的字母轉為小寫
print("s.lower() = {function}".format(function = s.lower()))s.lower() = abcada a
3、str.upper:將原字串的字母轉為大寫
print("s.upper() = {function}".format(function = s.upper()))s.upper() = ABCADA A
4、str.swapcase:將原字串的大寫小寫反轉
print("s.swapcase() = {function}".format(function = s.swapcase()))s.swapcase() = ABCAdA A
5、str.title:原字串內如果有特殊字元(包括數字)連線字母,則將特殊字元後的首個英文字母轉化為大寫形態,並返回新字串
print("s2.title() = {function}".format(function = s2.title()))s2.title() = 123A Abc Abcsaa S
6、str.center:str.center(寬度,填充字元) 將字串以居中的格式返回,若寬度值比len(s)小則返回原字串,填充以從左到右為規則,填充字元的預設值為空格,值可以自己更改
print("s2.center() = {function}".format(function = s2.center(19,'&')))print("s2.center() = {function}".format(function = s2.center(20,'&')))#s2 = 123a abc ABCSAa ss2.center() = &123a abc ABCSAa s s2.center() = &123a abc ABCSAa s &
7、str.expandtabs:str.expandtabs(tabsize = 8) 將原字串中以前的字元補滿8位(預設),tabsize的值從0-7即8位,在0-7中任意取值則預設tabsize = 8,此後往上+1,就相當於增加一個空格
print("s3.expandtabs ={function}".format(function = s3.expandtabs()))print("s3.expandtabs ={function}".format(function = s3.expandtabs(0)))print("s3.expandtabs ={function}".format(function = s3.expandtabs(5)))print("s3.expandtabs ={function}".format(function = s3.expandtabs(8)))print("s3.expandtabs ={function}".format(function = s3.expandtabs(9)))#s3 = "as b123"s3.expandtabs = as b123s3.expandtabs =as b123s3.expandtabs = as b123s3.expandtabs = as b123s3.expandtabs = as
除了上述舉例的,string函式還有許多實用的函式。
