扫描字符串
复制代码 代码示例:
#strpbrk(sStr1,sStr2)
sStr1 = 'cekjgdklab'
sStr2 = 'gka'
nPos = -1
for c in sStr1:
if c in sStr2:
nPos = sStr1.index(c)
break
print nPos
翻转字符串
复制代码 代码示例:
#strrev(sStr1)
sStr1 = 'abcdefg'
sStr1 = sStr1[::-1]
print sStr1
查找字符串
复制代码 代码示例:
#strstr(sStr1,sStr2)
sStr1 = 'abcdefg'
sStr2 = 'cde'
print sStr1.find(sStr2)
分割字符串
复制代码 代码示例:
#strtok(sStr1,sStr2)
sStr1 = 'ab,cde,fgh,ijk'
sStr2 = ','
sStr1 = sStr1[sStr1.find(sStr2) + 1:]
print sStr1
#或
s = 'ab,cde,fgh,ijk'
print(s.split(','))
连接字符串
复制代码 代码示例:
delimiter = ','
mylist = ['Brazil', 'Russia', 'India', 'China']
print delimiter.join(mylist)
PHP 中 addslashes 的实现
复制代码 代码示例:
def addslashes(s):
d = {'"':'"', "'":"'", " ":" ", "":"\"}
return ''.join(d.get(c, c) for c in s)
s = "John 'Johny' Doe (a.k.a. "Super Joe") "
print s
print addslashes(s)
只显示字母与数字
复制代码 代码示例:
def OnlyCharNum(s,oth=''):
s2 = s.lower();
fomart = 'abcdefghijklmnopqrstuvwxyz0123456789'
for c in s2:
if not c in fomart:
s = s.replace(c,'');
return s;
print(OnlyStr("a000 aa-b"))
