- Creating comment[/center]
Ofcourse Comments are pretty important at some points and to write it we will use # or """Comment""" tag so here's a code as an example of it
```#This is a comment```
Each comment line must have # tag like
```#Line 1
#Line 2
#Line 3```
and it can be done inside the script like this :
```foo = "Hello, World"; #It will print Hello, World
print foo```
or if you want to write multi-Lines with no # we can use the triple quotes
```"""This is many lines comments
Line 1
Line 2"""```
- More about print command
We can use Print() command in many different ways we can use + tag to connect words together for example
```print("Hello," + "World");```
it will print
```Hello,World```
The above sentence is not what we want , because it don't have space between Hello, and World so to fix this and
create a space using this print() method we can do it like
```print("Hello," + " World");```
it will print
```Hello, World```
Their is space because we added a space between " and World.
Another way we can use print(); function is by adding variable to the sentence so here is an example of it
```foo = "Hello,";
print(foo + " World");```
It will print out
```Hello, World```
Here is another example by adding 2 variables
```foo = "Hello,";
bar = " World";
print (foo + bar);```
It will print out
```Hello, World```
[center]- Input command
input() command is also important , It's like asking the user for anything you like for example
```input("What is your name ?");```
Then it will print
```What is your name ?```
and it will give you the ability to answer it but the answer will be in the same line in the question and to avoid
this you must know the following :
If you write
[*]\n , it will create a new line
[*]\t , it will create a new tab ( like 4 or 5 spaces )
[*]\' , it will allow you to add ' to the script
So That how it will be done
```input("What is your name ?\n");```
it will print out
```What is your name ?```
and then you will write in another line not in same line :)
[center]- If/else statments
if/else is one of the most important things in like any programming language .
it checks if the value in if is true it will return what you want and if it was false it will return the else
statment so here is an simple example
```number = 4;
if number == 4:
print(“We use if statment”);
else:
print(“We use else statment”);```
it will print
We use if statment
since the number is 4
Note : = sign is for declaring a variable but == sign is to check if value is equal to value :)
another example using else statment
myName = "roun"
if myName == "nuor":
print("We use if statment");
else:
print("We use else statment");
Since myName is not equal to nuor it will avoid if and go to else so it will print
We use else statment
now elif is like typing else if inside if/else statment and you can type it morethan one time ( as much as you want )
the script will check the condition of if if it’s true or false , then it will go to elif then else
so here is an example of it
```number = 5;
if number == 4:
print(“We used if statment”);
elif number == 5:
print(“We used elif statment”);
elif number != 5:
print(“We used elif statment”);
else:
print(“We used else statment”);```
So it will print the first elif statment because the number == to 5
We used elif statment
Thanks for Reading , in next tutorial i will post about import , defining , return ,for & while loops , Wish you understand it
