02: Learning to take inputs from user.

In this blog of code, we will learn to take basic inputs from the user and we shall apply them in the near future Insha'Allah...

# We have to verify that the input is a number or a string-

    # isdigit() Method -

val = '10'

print(val.isdigit())
print(int(val))
#using this method in a function
#creating a func whcih knows if the input is string or not;
#also, if it is in range or not !

def user_input():
    #initialization
    choice='Hah'
    defined_range= range(0,11)
    within_range= False

    while (choice.isdigit()==False) or (within_range==False):


        choice= input("INPUT A NUMBER B/W 0 TO 10: ")

        # CHECKING STRING 
        if choice.isdigit()==False:
            print("Sorry! Not a digit; kindly re-enter the value- ")

        '''Note that 
            we can also use 
                        not in [] method to check the data
                                but it is efficient if we already know the number of elements in a list.'''
        # CHECKING RANGE
        if choice.isdigit()==True:
            if int(choice) in defined_range:
                within_range= True
            else:
                print("Sorry! YOU are out of Range ")
                within_range=False
    return int(choice)



print(user_input())
