What if after writing a text inside the quotation marks we use full-stop or any other marks, does it affect the code?

Good question! The punctuation you add to a string, like a full-stop (period) or other marks, doesn’t affect the code itself, but it will change the actual content of the string.

For example, if you write:

print("This is a string.")

the output will include the period, showing: This is a string. However, if you write:

print("This is a string")

then the output will be This is a string without the period. The choice of punctuation is up to you and what you want to convey in that string.

Let me know if you have more questions!
