---|---|
find_anychar(string, chars[, index]) -> index of a character or -1 | |
rfind_anychar(string, chars[, index]) -> index of a character or -1 | |
splitany(s [,sep [,maxsplit [,negate]]]) -> list of strings | |
starts_with(s, start) -> 1/0 |
Function Details |
---|
find_anychar(string, chars, index=None, negate=0)find_anychar(string, chars[, index]) -> index of a character or -1 Find a character in string. chars is a list of characters to look for. Return the index of the first occurrence of any of the characters, or -1 if not found. index is the index where the search should start. By default, I search from the beginning of the string. |
rfind_anychar(string, chars, index=None, negate=0)rfind_anychar(string, chars[, index]) -> index of a character or -1 Find a character in string, looking from the end to the start. chars is a list of characters to look for. Return the index of the first occurrence of any of the characters, or -1 if not found. index is the index where the search should start. By default, I search from the end of the string. |
splitany(s, sep=' \t\n\x0b\x0c\r', maxsplit=None, negate=0)splitany(s [,sep [,maxsplit [,negate]]]) -> list of strings Split a string. Similar to string.split, except that this considers any one of the characters in sep to be a delimiter. If negate is true, then everything but sep will be a separator. |
starts_with(s, start)starts_with(s, start) -> 1/0 Return whether s begins with start. |
