Example Code

import pandas as pd
import pandera as pa
from icecream import ic
import pycountry
from pathlib import Path
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_and_validate_file(file):
    try:

        if Path(file).suffix == ".csv": 

            test_data = pd.read_csv('data_in/'+file)
            ic('Found csv file!')

        elif Path(file).suffix == ".xlsx":

            test_data = pd.read_excel('data_in/'+file, skiprows=1)
            ic('Found Excel file!')

Description
