Python

It is an interpreted programming language.

type()

This function determine the type of the parameter.

Example

>>> type(1)
<type 'int'>

str()

This function convert the parameter into a string.

Example

>>> str(1)
'1' 

len()

This function determines the lenght (amount of characters) within the parameter

Example

>>> len("Alejandro")
9

print()

This function prints the parameter

Example

>>> print("Hello, Good Morning")
​Hello, Good Morning

Strings

It is a literal data type that represent chains of characters mainly

Example

>>> "Hello World"
'Hello World'

​Integers

This is a numeric data type that represent integer numbers mainly

Example

>>> 120
120

​Float

This a numeric data type that represent floating point numbers

Example

>>> 1.2345
1.2345

​Boolean

This is a data type that represents either True or False. Useful for conditional statements

Example

>>> type(True)
<type 'bool'>

>>> type(False)
<type 'bool'>

>>> 0 == 0
True

>>> 1 == 0
False

​Boolean Operant "equals"   ==

This "function" determines equality for the given parameters

Example

>>> 0 == 0 
True

​Boolean Operant "different"  !=

This "function" determines if the given parameters are equal or not

Example

>>> 0 != 1 
True

Python is case sensitive

The python programming language is case sensitive

Example

>> "a" == "A"
False

Boolean operator "greater than"  >

This operator will compare if the left parameter is greater the right paramenter in order to come up with a Boolean result, it could be used in conjuntion with the equals operator in order to determine if the left parameter is greater than or equals to the right parameter

Example

>>> 100 > 60
True

Boolean operator "less than"  <

This operator will compare if the left parameter is less than the right paramenter in order to come up with a Boolean result, it could be used in conjuntion with the equals operator in order to determine if the left parameter is less than or equals to the right parameter

Example

>>> 200 < 150
False

>>> 200 <= 400/2
​True
