I want user to upload CSV file and the app should show the shape to the user. I am receiving the error '400 Bad Request: The browser (or proxy) sent a request that this server could not understand.'
from flask import Flask, request, render_template
import pandas as pd
import csv
app = Flask(__name__)
@app.route('/')
def my_form():
return render_template('form_ex.html')
@app.route('/home')
@app.route('/', methods = ['POST'])
def my_form_post():
if request.method == 'POST':
file = request.files['csv_data']
data = pd.read_csv(file)
print(data)
asa = str(data.shape)
return render_template('form_ex.html', shape=df.shape)
