Have an If-Statement but no 'else' after 'if'. Is the 'else' part necessary? i don't want to change the program (which is supposed to randomise 3 die 50 times and count how many matches there were) unless I need to. Mainly focused on 'else' after if statement

#Program 2#
#create a Yatzhee dice program#
import random

print("--------------------")
print("Yatzhee dice program")
print("--------------------")
print("")
print("Welcome to the Yatzhee Dice Program")
print("In this program the dice will get rolled 50 times and at the end we tell you how many matches you got.")
print("")
# before loop #

rolls = 50
total_matches = 0

# --- loop ---

for i in range(rolls): #randomise 50 times#
    die1 = random.randint(1, 6)
    die2 = random.randint(1, 6)#chooses a number from 1 to 6#
    die3 = random.randint(1, 6)

    print(die1, "|", die2, "|", die3)

    if die1 == die2 == die3:#If all three are the same.#
        print("****MATCH*****")#If statement inside for-loop so it adds up how many matches there were#
        total_matches += 1 #increases no. of matches by 1 each time there is a match#

#after loop#

print("")
print("The total number of matches was:", total_matches)#tells user how many matches there were#

  • Does your code work? If so, evidently you do not need an else clause. If not, tell us what the problem is. – khelwood Jan 29 '22 at 19:04
  • My code works but i was just unsure whether I needed an ‘else’ after the if statement – Harry Jan 29 '22 at 19:06

    No. Your code works without one, so clearly you do not need it. An else clause is completely optional. – khelwood Jan 29 '22 at 19:07
  • If it works, and you don't need to do anything for the case that the numbers are not equal, then I don't see any problem. – Amit Sides Jan 29 '22 at 19:08
  • Ok, thank you. It was just a question of wondering whether or not an ‘else’ was necessary – Harry Jan 29 '22 at 19:10

No, the else part is not necessary.

you can use only if 'N' times without using else statement, but it is good practice to use else and elif over if again and again. IF-else is used when we have 2 choice to do

if a==True:
   Do something1
else:
   Do something2
