Hello Guys!

I've started learning Python on my free time, and i wanted to teach you guys the basics.

Variables:
To declare a variable, its easier than C# and other languages.

All you have to do , is name the variable, and assign a value.

Example:

varA = 1
varB = 1.0
varC = "1"

In this case, we have declared the following.
varA is an integer. varB is a float. varC is a string.

Operators:
+ : This operator adds the value's on both sides of the operator.
Example:
1 + 2

Which will result in 3.

- : This operator substracts the right value, to the left value.
Example:
5 - 3

Which will result in 2.

* : This operator multiplies the value on both sides of the operator.
Example:
4 * 3

Which will result in 12.

/ : This operator will divide the left value, by the right value
Example:
12 / 3

Which will result in 4.

% : This operator will divide the left value, by the right value, and returns the remainder.
Example:
4 % 2

Which will result in 0.

Comparators:
== = If the value on the left side, and the right side are both equal, it returns true. Else, it returns false.
Example:
if varA == varB:
print("varA is equal to varB")

!= = If the value on the left side, and the right side are different, it returns true. Else, it returns false.
Example:
if varA != varB:
print("varA is different than varB")

> = If the value on the left side, is greater than the right value, it returns true. Else, it returns false.
Example:
if varA > varB:
print("varA is greater than varB")
else:
print("varB is greater or equal than varA")

< = If the value on the left side, is lower than the right value, it returns true. Else, it returns false.
Example:
if varA < varB:
print("varA is smaller than varB")
else:
print("varB is smaller or equal than varA")

>= = If the value on the left side, is greater or equal than the right value, it returns true. Else, it returns false.
Example:
if varA >= varB:
print("varA is greater or equal than varB")
else:
print("varA is smaller than varB")

<= = If the value on the left side, is smaller or equal than the right value, it returns true. Else, it returns false.
Example:
if varA <= varB:
print("varA is smaller or equal than varB")
else:
print("varA is greater than varB")

Statements:
if = Used to check wheter a condition is true or false
Example:
if varA == varB:
print("varA is equal than varB")

else = Used to check wheter a condition is true or false, when the IF was false
Example:
if varA == varB:
print("varA is equal than varB")
else:
print("varA is not equal than varB")

elif = Used to check wheter a condition is true or false, when the IF was false, and there are more than two results
Example:
if varA > varB:
print("varA is greater than varB")
elif varA < varB:
print("varA is smaller than varB")
else:
print("varA is equal than varB")

I will post part 2 in the future :)
