In the first instance we are going to replace all instances of a British Pound sign in a given sentence with that of a dollar sign. Thankfully Python has this covered, making it simple little program.
First we create our variable Sentence and assign it with input from our user.
Sentence = input(“Please enter a sentence:”)
Then we use the .replace() method to do the work for us.
We give it two arguments; the symbol we want to replace followed by what we want it replaced with. In this case its replace all instances of £ with $
We assign the results to a new variable with the very same name; Sentence
Sentence = Sentence.replace(‘£’,’$’) #don’t forget the comma
Now all that is left is to print the variable Sentence to the screen
print(Sentence)
The full program:
Sentence = input(“Please enter a sentence:”)
Sentence = Sentence.replace(‘£’,’$’)
print(Sentence)
We could of course use this little program to replace a full word; like replace apple with orange
Our first line will remain the same.
Sentence = input(“Please enter a sentence:”)
Our second line of course will be changed to meet the new criteria
Sentence = Sentence.replace(‘apple’, ‘orange’)
We need to take account that someone may capitalize Apple and Orange, so we add a line to our code to capture this.
Sentence = Sentence.replace(‘Apple’, ‘Orange’)
And of course we print just like the last program
print(Sentence)
Full Program:
Sentence = input(“Please enter a sentence:”)
Sentence = Sentence.replace(‘apple’, ‘orange’)
Sentence = Sentence.replace(‘Apple’, ‘Orange’)
print(Sentence)
Lets input a sentence like, I do love an apple in the morning. You should eat an Apple every day…
Simple!
