Easy Sunday Excel Challenge

Challenge Description
Easy Sunday Excel Challenge
⭐ ⭐Count Complete and OK Invoices
Solutions
Logic:
Reads the workbook range needed for the challenge
Uses direct text-pattern extraction instead of manual cleanup
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
path = "2026-02-08/Challenge 102.xlsx"
input = pd.read_excel(path, usecols="B:C", skiprows=1, nrows=11)
test = pd.read_excel(path, usecols="E", skiprows=2, nrows=1, header=None).iloc[0, 0]
def clean_string(s):
return re.sub(r'[^a-z]+', ' ', s.lower())
res = input[input.Status.apply(lambda s:
"complete" in clean_string(s)
and "ok" in clean_string(s)
and not re.search(r'not ok|risk|hold|incomplete', clean_string(s))
)]
print(len(res) == test)
# TrueLogic:
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 moderate:
It combines familiar Excel-style logic with at least one non-trivial reshape, grouping, or parsing step.
The answer depends on getting the output layout exactly right.
