3 | sStr2 = '123bc' |
4 | n = 3 |
5 | print cmp(sStr1[0:n],sStr2[0:n]) |
複製指定長度的字元

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:] |
