Type Error: can only concatenate str (not "float") to str

Question

My Error is:

web.open("https://web.whatsapp.com/send?phone=" +lead+ "&text=" +message)
TypeError: can only concatenate str (not "float") to str

I am trying to automate the Whatsapp message and it shows this error. I am not able to understand what it means.

import pyautogui as pg
import webbrowser as web
import time
import pandas as pd
data = pd.read_csv("phone numbers.csv")
data_dict = data.to_dict('list')
leads = data_dict['Number']
messages = data_dict['Message']
combo = zip(leads,messages)
first = True
for lead,message in combo:
    time.sleep(4)
    web.open("https://web.whatsapp.com/send?phone="+lead+"&text="+message)
    if first:
        time.sleep(6)
        first=False
    width,height = pg.size()
    pg.click(width/2,height/2)
    time.sleep(8)
    pg.press('enter')
    time.sleep(8)
    pg.hotkey('ctrl', 'w')

You need to convert lead to it's string representation first:

web.open("https://web.whatsapp.com/send?phone="+str(lead)+"&text="+message)

The error you are seeing is because your leadvariable is a number, or float type of variable, not a string.

"Concatenate" is what you are trying to do with the + in the web.open line of code - you are generating a new string by adding multiple strings together.

However, Python doesn't allow you to concatenate a number or other non-string type to a string without explicitly converting it first.

web.open("https://web.whatsapp.com/send?phone="+str(lead)+"&text="+message)
