#function username which takes two arguments 
#first_name and the last_name
def user_name(first_name, last_name) :
    '''
    new name 
    *concatenating the string using + operator
    *[:3] -> specifies taking only 3 letters 
    *from the starting of the string
    '''
    new_name = first_name[:3]+last_name[:3]
    #then return this new name
    return new_name
    
#now calling this function with the test cases.

print(user_name("bob","taft"))
print(user_name("Ralph","Waldo"))


#making program to work with this
#taking input for the first name and last name 
first_name = input("Enter first name : ")
last_name = input("Enter the last name : ")
#print the new name by calling the function user_name(-,-)
print("New username : ",user_name(first_name,last_name))
