In the particular case where you know the number of positions that you want to remove from the dataframe column, you can use string indexing inside a lambda function to get rid of that parts: Last character: data['result'] = data['result'].map(lambda x: str(x)[:-1]) First two characters:
newStr = extractAfter(str,pat) extracts the substring that begins after the substring specified by pat and ends with the last character of str. If pat occurs multiple times in str , then newStr is str from the first occurrence of pat to the end.

Python provides string methods that allows us to chop a string up according to delimiters that we can specify. In other words, we can tell Python to look for a certain substring within our target string, and split the target string up around that sub-string.
newStr = split (str,delimiter,dim) divides each element of str into a vector oriented along the dimension specified by dim. example. [newStr,match] = split (___) additionally returns an array, match, that contains all occurrences of delimiters at which the split function splits str.
