python - Check if the string contains the substring returns true when its actually false

Question

Is it a problem with my editor or what stupid mistake am I making ? Here is the screen-shot

This code returns true and it actually should

a = "https://www.reddit.com/comments/ado0ym/use_reddit_coins_to_award_gold_to_your_favorite/"
b = "use_reddit_coins_to_award_gold_to_your_favorite"

if b in a:
    print("true")

# Results return true

But this must return False but returns True

a = "https: // www.reddit.com/comments/ado0ym/"
b = "use_reddit_coins_to_award_gold_to_your_favorite"

if b in a:
    print("true")

# Results return true

Answer 1

works fine: First one returns True, second one returns False:

If you're running your code, it should correctly print true because the first set is True, and then prints nothing after that:

true

if both were True, you would see

true
true

See below:

a = "https://www.reddit.com/comments/ado0ym/use_reddit_coins_to_award_gold_to_your_favorite/"
b = "use_reddit_coins_to_award_gold_to_your_favorite"

print (b in a)



a = "https: // www.reddit.com/comments/ado0ym/"
b = "use_reddit_coins_to_award_gold_to_your_favorite"

print (b in a)    

Output:

True
False
