python3 parse string
Given field_name as returned by parse() (see above), convert it to an object to be formatted. Returns a tuple (obj, used_key). The default version takes strings of the form defined in PEP 3101, such as “0[name]” or “label.title”. args and kwargs are as p,Given field_name as returned by parse() (see above), convert it to an object to be formatted.

UNICODE and its embedded counterpart (?u)), but these are redundant in Python 3 since matches are Unicode by defa, "2.7.0_bf4fda703454".split("_") gives a list of strings: In [1]: "2.7.0_bf4fda703454".split("_") Out[1]: ['2.7.0', 'bf4fda703454']. This splits the string at every underscore. If you want it to stop, You can use the shlex module. Example: import shlex print(shlex.split("C C .0033 .0016 'International Tables Vol C Tables 4.2.6.8 and 6.1.1.4' C"))., re.match starts searching from the beginning of the line, that's why you are not getting any match. Use re.search instead: >>> m = re.search(r'(-d+),(-d+)', my_str) >>> if m: ... _len, _pre = map(int, m.groups()) ... >>,Python 3 String split() Method - Learning Python 3 in simple and easy steps : A beginner's tutorial containing complete knowledge of Python 3 Syntax Object Oriented Language, Environment Setup, Basic Syntax, Variable Types, Basic Operators, Decision M,Python3 split()方法Python3 字符串描述split()通过指定分隔符对字符串进行切片，如果参数num 有指定值，则仅分隔num 个子字符串语法split()方法语法： str.split(str='', num=string.count(str)) 参数str -- 分隔符，默认为所有的空字符，包括空格、换行(-n)、制表符(-t)等。 num -- 分割次数。 .. , Python has several built-in functions associated with the string data type.
