Excel to Python: LEFT Function - A Complete Guide | Mito
Install Mito to start using Excel formulas in Python. # Import the mitosheet Excel functions from mitosheet.public.v3 import *; # Use Mito's LEFT function # Note: We don't need to first convert the column to a # string because Mito's LEFT function does so automatically df['extracted'] = LEFT(df['text_column'], 2)

If I remember my QBasic, right, left and mid do something like this:
>>> s = '123456789'
>>> s[-2:]
'89'
>>> s[:2]
'12'
>>> s[4:6]
'56'

String Functions in Python with Examples
This tutorial explains various string (character) functions used in Python, with examples. To manipulate strings and character values, python has several built-in functions. The table below shows many common string functions in Python along with their descriptions and their equivalent functions in MS Excel. If you are intermediate MS Excel users, you must have used LEFT, RIGHT and MID Functions.

Slice a string in python (right, left, mid equivalents) - InterviewQs
A step-by-step Python code example that shows how to slice a string (right, left, mid equivalents). Provided by InterviewQs, a mailing list for coding and data interview problems.

You're looking for slicing:
>>> s = "Hello World!"
>>> print s[2:] # From the second (third) letter, print the whole string
llo World!
>>> print s[2:5] # Print from the second (third) letter to the fifth string
llo
>>> print s[-2:] # Print from right to left
d!
>>> print s[::2] # Print every second letter
HloWrd
So for your example:
>>> s = 'col555'
>>> print s[3:]
555

If you know it will always be col followed by some numbers:
>>> int('col1234'[3:])

It does not prefer the right-hand side to the left. print(True or False) will output True. It’s related to a concept called short circuiting, whereby the interpreter essentially stops evaluating statements as soon as it can. With True or False, being an OR statement, as long as either one is true, the condition passes. Since True comes first, there’s no need to evaluate the second part. (This makes more sense when the things being evaluated are actual conditions and not just bare booleans). In your examples, the left-hand side is False/false-like, so it continues evaluating, which is why it outputs the right-hand side.

How to Get Parts of a String in Python | Delft Stack
February 15, 2024 - As you can see from the above example, we didn’t mention the ending point for the slicing method. We only specified the starting point, and it sliced the string until the end because, by default, the value was the last element. Now, suppose we only want to get the last element of the string using the same method. We can quickly achieve this using the following method. # python originalString = "Slicing the string with Python" lastElement = originalString[-1] print("The last element collected is ", lastElement)
