4.count()
name = 'liuliuliullllluuuuggg'
res = name.count('l')#统计l出现的次数 res = name.count('l'0,10)从0-10中字符串查找。
print (res)
5.endswith 判断是不是以什么字符结尾
name = 'liu'
res = name.endswith('u',0,3) #判断liu是否以u结尾,是返回true,不是返回false.
print (res)
6.find()
name = 'liuliuliullllluuuuggg'
res = name.find('l',0,n)#查找l所在的字符串位置,没有返回-1
res = name.index('l',0,n)#没有找到报错
print (res)
7.format
name = 'liuguisheng{0} {1}'
res = name.format('handsome\t','age:28')
print (res)

name = 'liuguisheng {name} {id}'
res = name.format(name='liuguisheng',id='28')
print (res)
***********************************************
8..join 字符串拼接
li=['l','g','s']
res = "".join(li)
print(res)
返回lgs
