Types are a category for things within Python with which Python will work. Types are integers,float,strings,tuples,lists and dictionaries.
Integers
Whole numbers from negative infinity to infinity, such as 1, 0, -5, etc.
Integers are numeric values and can be stored, manipulated, and expressed inside variables without quotes.
Example:
x=5
print (x)
>>>5
Float
Short for "floating point number," any rational number, usually used with decimals such as 2.8 or 3.14159.
Strings
A set of letters, numbers, or other characters.
Strings are a type. They are the basic unit of text in Python and all the other types except integers may contain strings.
Example:
x="Hello World"
print (x)
>>>Hello World
Tuples
A list with a fixed number of elements. ie x=(1,2,3) parentheses makes it a tuple.
A tuple is an unchangeable sequence of values.
Example:
x = ("element 1", "element 2", "element 3")
Lists
A list is a changeable sequence of data. A list is contained by square brackets i.e. [1,2,3]
Example:
x=[1,2,3]
print (x)
>>>[1,2,3]
Dictionaries
A type with multiple elements i.e. x = {1: 'a','b': 2,3: 3} where you address the elements with, e.g., a text.
Example:
x={'Hello':'hola', 'Bye':'adios'}
print(x)
>>> {'Hello':'hola', 'Bye':'adios'}

Dictionaries
A type with multiple elements i.e. x = {1: ‘a’,’b’: 2,3: 3} where you address the elements with, e.g., a text.
Example:
x={‘Hello’:’hola’, ‘Bye’:’adios’}
print(x)
>>> {‘Hello’:’hola’, ‘Bye’:’adios’}
