TypeError: can only concatenate str (not "int") to str in number loops

Question

I am attempting to write a bot to preform automated actions on Discord. I have written the following code to do so:

import clipboard
import time

numnum = input("  What do you want the delay from each next number? (in seconds) \n\t    Please type it here:    ")
startingnum = input("   What do you want the starting number to be? \n\t    Please type it here:    ")
for i in range startingnum , 99999999999999):
    print('Your clip Board is set to ' + i )
    clipboard.copy(i)
    time.sleep(numnum)
print('terminal will close in 5 seconds')
time.sleep(5)

However, this code generates the following error:

TypeError: can only concatenate str (not "int") to str

I am not sure why this error occurs, could someone give me insight into why this error happens in my code?

This is a pretty straight forward syntax problem You are trying to concatenate a string 'Your clip Board...' and an integer i

In order to concatenate correctly, typecast the integer to a string.

for i in range (startingnum , 100):
    #typecast int --> str using the built in str() function
    print('Your clip Board is set to ' + str(i) )

Convert i to a string

import clipboard
import time

numnum = input("  What do you want the delay from each next number? (in seconds) \n\t    Please type it here:    ")
startingnum = input("   What do you want the starting number to be? \n\t    Please type it here:    ")
for i in range startingnum , 99999999999999):
    print('Your clip Board is set to ' + str(i) )
    clipboard.copy(i)
    time.sleep(numnum)
print('terminal will close in 5 seconds')
time.sleep(5)

Here are the 2 changes you need to make:

As you are requesting for user input, numnum and startingnum will store string values and not int values. So use int(input(...)) for an integer type input.
When you are combining string and int, use a comma(,) instead of +.

Here is the code snippet:

import clipboard
import time

numnum = int(input("  What do you want the delay from each next number? (in seconds) \n\t    Please type it here:    ")) #Change 1
startingnum = int(input("   What do you want the starting number to be? \n\t    Please type it here:    "))
for i in range(startingnum , 99999999999999):
    print('Your clip Board is set to ' , i ) #Change2
    clipboard.copy(i)
    time.sleep(numnum)
print('terminal will close in 5 seconds')
time.sleep(5)
