student_number = []
student_name ["mark","rob","Jessica"]

Index is used to access elements in a list
for example:
student_name[0] == "Mark"
student_name[1] == "rob"
student_name[-1]="Jessica"

Replacing an element in list
Student_name[0] ="James"
student_name ["James","rob","Jessica"]

Add element to a list:
student_name.append("mark")
student_name ["James","rob","Jessica","mark"]

Checking element in list:
"mark" in student_name == True

number = 5
if number == 5:
     print("Number is 5")
else:
    print("Number is Not 5")


Truthy and Falsy Value:

Eg; Any number other than 0 has truthy value
Eg: Empty string is falsy value

python_book = True
if not python_book:
    print("This will not execute")


Multiple If Conditions:
number = 3
python_book = True

if number = =3 and python_book:
    print("This will work")

if number == 17 or python_book:
     print("This will work too")

Ternary if Statements
a = 1
b =2
"bigger" if a > b else "smaller"
Note: This can be super helpful in list comprehension.

Numbers
Integer = Number
Float = Decimal Number

Code Example:
Integer:
answer = 42
Float:
pi = 3.14159
Complex Number (Python 3):

Easy TypeCast
int(pi) == 3
float(answer) == 42.0

String:
Python 2: ASCII
Python 3: Unicode
String Can be defined using:
'Jello World' = "Jello World" = """Jello World """
Example:
"hello.capatalize() == "Hello"
"hello".replace("e" , "a") == "Hallo"
"hello".isalpha() == True
"123".isdigit()== True #Useful when converting to Int
Advanced
"Some, csv, values".split(",") = ["some","csv","values"]

String Format
name = "PythonGo"
Machine = 'BAL"

"Great meeting you {0}. I am {1}".format(name,machine)

Python 3.6
String Interpolation:
f"Great meeting you {name}. I am {machine}


Boolean and None:

python_book = True
java_book = False

Used often with If Statement
Note - Both Start with Capital Letter T and Capital F

int(python_book) == 1
int(java_book)==0
ste(python_book) == "True"

aliens_found= None
