python 的字符串切片
Slicing Strings for python
Write a function slice_from(string, start, end)
which returns the characters in string
from index start
up to, but not including, index end
.
我的代码中有这个:
part = s[1:]
print(part)
我的工作计算机上没有安装 python,所以我无法对其进行测试,但这应该可以:
def slice_from(string, start, end):
returnVal = "";
for x in range (start, end -1):
returnVal += string [x];
return returnVal;
此外,阅读更多内容可能会有所帮助 Python or learning Python online for free at someplace like CodeAcademy
