Im trying to replace a word in python, but another word with same letter format got replaced

example :

initial        : 'bg bgt'
goal           : 'bang banget'
current result : 'bang bangt'

heres what my code currently looks like:

def slangwords(kalimat):words = kalimat.split(' ')for word in words:if any(x in word for x in "bg"):kalimat = kalimat.replace("bg","bang")if any(x in word for x in "bgt"):kalimat = kalimat.replace("bgt","banget")return kalimatprint(slangwords('bg bgt'))

n ill appreciate more if u can show me how to replace these slangword more effective and efficient, thanks

That is because you replace bg before bgt (which is a bigger substring), you need to change the order.

Also, you don't need if any(x in word for x in "bg"), that checks if every letter is present in the word and not if the substring is present in the same order, plus, you don't need any verification before using str.replace, if the strin isn't there, it won't do anything

You just need

def slangwords(kalimat):return kalimat.replace("bgt", "banget").replace("bg", "bang")

Better and not order-dependent

Use a dictionnary, and replace each word with its substitute

def slangwords(kalimat):replacements = {'bg': 'bang','bgt': 'banget'}words = kalimat.split(' ')for i, word in enumerate(words):words[i] = replacements.get(word, word)return " ".join(words)
