Is String Mutable?
You may recall something about mutable and immutable data types. Immutable cannot be changed .
But what about strings? They are immutable. We cannot change a string directly, only with special operations. We will not have knowledge of the outcome unless we make an attempt. Therefore, let us examine this example.
string = "What does it really take to be first past the post?" string[0] = 'k'
TypeError 😔
It is difficult to disagree with the assertion that modifying strings is essential. Just as individuals can alter their viewpoints, we should permit strings to undergo similar changes.
The replace() method was implemented to solve this problem. It has the following syntax: string.replace(old_word, new_word). By the way, each method that can be implemented for string just creates new string because the current one cannot be modified. Look at the example in which I want to change seafood to fish:
string = "I would like to order seafood" # I changed my mind and want to order fish now new_string = string.replace('seafood','fish') # The previous order print(string) # The current order print(new_string)

As I said before, practice is the key to success; hence, here is another occasion to do it!
Correct the mistakes in the sentences string1, string2, and string3 to make them truthful. You should receive the following results:
"Paris is the capital of France"."Brasilia is located in South America"."Monkeys eat bananas".
