The script is running without error.

let me type something to show you. A block of string.

This tutorial is for string.

Lets run once again you can run without error and commenting is successful.

lets do some operation on string.

x = hello within double quote.
y = world within single quote.

whether the word is type in double quote or single quote. It is always a string.

Let type.

print(x).
print(y).

so lets run this code. Use Shift F 10 to run the code.

you can see the print hello. world. as we define.

you can see that double quote or single quote. python take it as string.

lets do some operation. There are in-built method. you can click dot next to x and you can see many method supported in PI charm.

lets select capitalize() in x as well as in y variable.

run this code you will see that staring letter change to capital letter.

Lets copy the print line of code.
Change from capitalize to UPPER().

run the code using shift F 10 and you will see the result as all string change to UPPERCASE.

let do addition of two string.
we can use + operator and add two string.
lets take a new variable Z = X + Y
print Z.

use shift F 10 to run the code. Now you will see both sting join. Onething you observe here that both string join end to end.
To have a space between the string. introduce a single quote. with a space between the operation. of x and y .using + operators. which is called string concatenation.

print Z. run using shift F10 and you will see a space between the string.


we can apply capitalize to z. it affect only the starting letter.

run the code using shift F10 and check the result.

Copy the code again. delete the operation as it is not neccessary to do every time.

Now you can apply upper to z. it affect onlys all the letter to upper case.

run the code using shift F10 and check the result.
