how can I write a code that replaces each consonant in a file with a vowel? I tried a code that only works for the last consonant. I don't know why and I am getting tired of trying alone

A coding nightmare!!!

this is the code: text = "this is fun" vowel= ["a","e","i","o","u"] def translate(file): for i in file: if i in file and i not in vowel: a= file.replace (i,"o") return a print(translate(text)) please help me find the reason why it only works for the last consonant.

your code doesnt work. Try this: text = "this is fun" vowel= ["a","e","i","o","u"] def translate(file): a = "" for i in file: if i not in vowel: a+="o" else: a+=i return a print(translate(text))

Pavel thanks. a="" is a string that changes value for each non vowel element that of the file parameter. but I don't understand how the interpreter knows that a replaces the consonants. can you pls explain that part of the code?

okay, lets see how code work step by step. At firts we created string variable with name @a@ and its value is empty string. a = "" Next, we create a loop, which iterate over @file@ function parameter. In our case that mean that body loop will execute 11 times (because len(file) in our case = len("this is fun") and in every iteration @i@ will take corresponding value: 0 - t 1- h 2 - i 3 - s ....etc for i in file: in every iteration we check that the current letter of our text (@i@) doesnt contains in @vowel@ list. If its true, we append to our answer string @a@ letter "o", in other case we append @i@ value. if i not in vowel: a+="o" else: a+=i Remember, this works in every iteration of the loop! i = 't' True a="o" i='h' True a="oo" i='i' False a="ooi" i='s' True. a="ooio" ........ And after all iterations we return @a@ value from our function: return a

hi wa dz. I've been trying to prime myself by solving some Python problems online. building algorithms like; bubble, merge, quick sort etc. it has been all about cramming without really understanding my code. so I went back to smaller problems.
