< 0 未找到
Python
1 |
#strchr(sStr1,sStr2) |
2 |
sStr1 = 'strchr' |

nPos = sStr1.index(sStr2) |
5 |
print nPos |
比較字元串
Python
1 |
#strcmp(sStr1,sStr2) |
2 |
sStr1 = 'strchr' |
3 |
sStr2 = 'strch' |
4 |
print cmp(sStr1,sStr2) |
掃描字元串是否包含指定的字元
Python
1 |
#strspn(sStr1,sStr2) |
2 |
sStr1 = '12345678' |
3 |
sStr2 = '456' |
4 |
#sStr1 and chars both in sStr1 and sStr2 |
5 |
print len(sStr1 and sStr2) |
字元串長度
Python
1 |
#strlen(sStr1) |
2 |
sStr1 = 'strlen' |
3 |
print len(sStr1) |
將字元串中的大小寫轉換
Python
1 |
#strlwr(sStr1) |
2 |
sStr1 = 'JCstrlwr' |
3 |
sStr1 = sStr1.upper() |
4 |
#sStr1 = sStr1.lower() |
5 |
print sStr1 |
追加指定長度的字元串
Python
1 |
#strncat(sStr1,sStr2,n) |
2 |
sStr1 = '12345' |
3 |
sStr2 = 'abcdef' |
4 |
n = 3 |
5 |
sStr1 += sStr2[0:n] |
6 |
print sStr1 |
字元串指定長度比較
Python
1 |
#strncmp(sStr1,sStr2,n) |
2 |
sStr1 = '12345' |
3 |
sStr2 = '123bc' |
4 |
n = 3 |
5 |
print cmp(sStr1[0:n],sStr2[0:n]) |
複製指定長度的字元
Python
1 |
#strncpy(sStr1,sStr2,n) |
2 |
sStr1 = '' |
3 |
sStr2 = '12345' |
4 |
n = 3 |
5 |
sStr1 = sStr2[0:n] |
6 |
print sStr1 |
將字元串前n個字元替換為指定的字元
Python
1 |
#strnset(sStr1,ch,n) |
2 |
sStr1 = '12345' |
3 |
ch = 'r' |
4 |
n = 3 |
5 |
sStr1 = n * ch + sStr1[3:] |
6 |
print sStr1 |
掃描字元串
Python
1 |
#strpbrk(sStr1,sStr2) |
2 |
sStr1 = 'cekjgdklab' |
3 |
sStr2 = 'gka' |
4 |
nPos = -1 |
5 |
for c in sStr1: |
6 |
if c in sStr2: |
7 |
nPos = sStr1.index(c) |
8 |
break |
9 |
print nPos |
翻轉字元串
Python
1 |
#strrev(sStr1) |
2 |
sStr1 = 'abcdefg' |
3 |
sStr1 = sStr1[::-1] |
4 |
print sStr1 |
查找字元串
Python
1 |
#strstr(sStr1,sStr2) |
2 |
sStr1 = 'abcdefg' |
3 |
sStr2 = 'cde' |
4 |
print sStr1.find(sStr2) |
分割字元串
Python
1 |
#strtok(sStr1,sStr2) |
2 |
sStr1 = 'ab,cde,fgh,ijk' |
3 |
sStr2 = ',' |
4 |
sStr1 = sStr1[sStr1.find(sStr2) + 1:] |
5 |
print sStr1 |
6 |
或者 |
7 |
s = 'ab,cde,fgh,ijk' |
8 |
print(s.split(',')) |
連接字元串
Python
1 |
delimiter = ',' |
2 |
mylist = ['Brazil', 'Russia', 'India', 'China'] |
3 |
print delimiter.join(mylist) |
PHP 中 addslashes 的實現
Python
1 |
def addslashes(s): |
2 |
d = {'"':'\\"', "'":"\\'", "\0":"\\\0", "\\":"\\\\"} |
3 |
return ''.join(d.get(c, c) for c in s) |
4 |
5 |
s = "John 'Johny' Doe (a.k.a. \"Super Joe\")\\\0" |
6 |
print s |
7 |
print addslashes(s) |
只顯示字母與數字
Python

def OnlyCharNum(s,oth=''): |
2 |
s2 = s.lower(); |
3 |
fomart = 'abcdefghijklmnopqrstuvwxyz0123456789' |
4 |
for c in s2: |
5 |
if not c in fomart: |
6 |
s = s.replace(c,''); |
7 |
return s; |
8 |
9 |
print(OnlyStr("a000 aa-b")) |
