Solutions

  • Logic:

    • Applies the workbook rule directly and shapes the expected output

  • Strengths:

    • The R solution stays compact and mirrors the workbook logic closely.

  • Areas for Improvement:

    • The code assumes the workbook layout and named ranges remain stable.

  • Gem:

    • The best part of the solution is choosing a tidy intermediate shape before producing the final answer.
import pandas as pd
import re
import numpy as np

input = pd.read_excel('files/Excel Challenge 2nd June.xlsx', usecols='C', skiprows=1, nrows = 6)
test  = pd.read_excel('files/Excel Challenge 2nd June.xlsx', usecols='D', skiprows=1, nrows = 6)

test['Last Correct Order'] = test['Last Correct Order'].replace(np.nan, '', regex=True)

def extract_after_last_letter(s):
    match = list(re.finditer(r'[A-Za-z]', s))
    if match:
        last_letter_pos = match[-1].end()
        return s[last_letter_pos:] if last_letter_pos < len(s) else ''
    return ''

input['answer'] = input['Customers & Orders'].apply(extract_after_last_letter)

print(input.merge(test, left_index=True, right_index=True))

#                     Customers & Orders  answer Last Correct Order
# 0                  Emily15423Jake56243   56243              56243

# 5  Orders #564 and #5862 were rejected

  • Logic:

    • Reads the workbook range needed for the challenge

    • Uses direct text-pattern extraction instead of manual cleanup

  • Strengths:

    • The Python version keeps the same rule in a direct pandas-oriented workflow.

  • Areas for Improvement:

    • As with the R version, any workbook layout change would require small adjustments.

  • Gem:

    • The implementation stays close to the stated challenge instead of adding unnecessary complexity.

Difficulty Level

This task is easy to moderate:

  • The business rule is readable, but the workbook still needs a few careful transformation steps.
