str.split, str.rsplit re.split str.partition, str.rpartition Python split/rsplit methods The split methods cut a string into parts based on the given separator parameter. With the optional second parameter we can control how many times the string is cut. str.split([sep[, maxsplit]]) The...
string = 'Twelve:12 Eighty nine:89 Nine:9.' pattern = '\d+'# maxsplit = 1# split only at the first occurrence result = re.split(pattern, string, 1) print(result)# 输出: ['Twelve:', ' Eighty nine:89 Nine:9.'] 顺便说一下,maxsplit默认值为0;默认值为0。意味着拆分所有匹配的结果。
Split the string at the first occurrence ofsep, and return a 3-tuple containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return a 3-tuple containing the string itself, followed by two empty strings. mystr ='hell...
>>> line.rsplit("|", maxsplit=1) ['Rubber duck|5', '10'] This splits from the right-hand side of the string. Or you can think of it as a reverse split, splitting from the end of the string.So here we're splitting on the last occurrence of the pipe character....
Split string on last delimiter occurrence. Write a Python program to split a string on the last occurrence of the delimiter. Sample Solution: Python Code: # Define a string 'str1' containing a comma-separated list of characters.str1="w,3,r,e,s,o,u,r,c,e"# Split the string 'str1...
#!/usr/bin/python str = "Line1-abcdef \nLine2-abc \nLine4-abcd"; print str.split( ); print str.split(' ', 1 ); 以上实例输出结果如下: ['Line1-abcdef', 'Line2-abc', 'Line4-abcd'] ['Line1-abcdef', '\nLine2-abc \nLine4-abcd'] 1. 2. 3. 4. 5. 6. 7. 8. de...
A string containing all characters that are considered whitespace. On most systems this includes the characters space, tab, linefeed, return, formfeed, and vertical tab. Do not change its definition — the effect on the routines strip() and split() is undefined. ...

os.path.split(path) 将path分割成目录和文件名二元组返回 os.path.dirname(path) 返回path的目录。其实就是os.path.split(path)的第一个元素 os.path.basename(path) 返回path最后的文件名。如何path以/或\结尾,那么就会返回空值。即os.path.split(path)的第二个元素 ...
