What's the code if we want to trim the string

Question

I am kind of noob in python and struck in middle of code. I want to trim my string. For example- my string is "bangalore store 1321" and i want to trim it to "banglore"

That is not trimming. Trimming means removing spaces on the edges of the string. — Marvin, Dec 23 '18 at 15:52

Looks like you want to keep the first word (which is not "trimming" though). So you do two things

break the string into a list of words (where "word" is something separated by spaces)

take the first element of that list

words = mystring.split(' ')
result = words[0]

For a slicing answer:

def sub_string(str, start,end):
    return str[start:end]

You can also use split, by definition, this splits by spaces, if any other delimiter needed, you can identity it inside the split arguments split(',')

def split_string(str):
    return str.split()

This function will return an array of strings. Choose whichever you want from this array

@Nitin you add a new question. Mention what is the data that you have and output you require. Also update what you have tried so far. – Bitto Bennichan Dec 26 '18 at 18:31
I am sorry. That's the same question i am looking for. – Nitin Dec 27 '18 at 18:13
@Nitin You need to access the first element from that list. So use str.split(' ')[0] – Bitto Bennichan Dec 27 '18 at 18:28

You can use str's partition method to avoid creating a list like str.split

>>> first_word, _, _ = s.partition(' ')  # _ is a convention for a throwaway variable
>>> print(first_word)
bangalore

str.partition takes one argument - the separator - and returns the parts of the string before and after the first occurrence of the separator.
