minimum_value = float(2.2)
price = float(1.99)
def cheese_order():
user_order = float(input("enter ur order mount :"))
if user_order < minimum_value:
print ("ur amount's less than the minimum. pls enter a higher amount. ")
elif user_order > maximum_value:
print("ur amount's more than our maximum, pls enter a less amount. ")
elif user_order.isdigit():
return print(" the price is", price ,"*", user_order ,"=", price * user_order)
else:
print("pls enter the amount in digit & try again. ")

Answer 1

you create a variable "maximum_vaLue" and then refer to "maximum_value" which are not the same
isdigit() is only for strings not floats and should be done first thing when taking user input before converting to float
