Learn Python like a Professional! Take You from 0 to Hero

In this Python lecture, we will learn about the Numbers.

Type of  Numbers 

There are three numeric types in Python

• Integer
• float
• Complex

we focus on the Integer & floating point number.

Basic Arithmetic 

1. Addition

1 + 2

>>3

2 + 3

>>5


2. Subtraction

2 - 1

>>1

3 - 2

>>1


3. Multiplication

1 * 2

>>2

2 * 3

>>6


4. Division

2 / 5

>>0.4

5 / 7

>>0.7142857142857143


5. Power

2 ** 3

>>8

3 ** 4

>>81


6. Order of Operation

1 + 2 * 3

>>7

(1+2)*(3+4)

>>21


7. Assign Value

x=2
y=3

x

>>2

y

>>3

z=x+y

z

>>5


8. Rules for Python Variable Name

• Must begin with a letter (a - z, A - B) or underscore (_)
• Other characters can be letters, numbers or _
• Case Sensitive
• Can be any (reasonable) length
• There are some reserved words which you cannot use as a variable name because Python uses them for other things.

principal=10

interest_rate=2

time=3

simple_interest=principal * interest_rate * time / 100

simple_interest

>>0.6

What is the importance of this lecture?

• +  is the sign of addition.
• -  is the sign of Subtraction.
• *  is the sign of Multiplication.
• /  is the sign of Division.
• **  is the sign of Power.
• Shift + Enter is used to run the code in jupyter notebook. 
• TAB is used to Autocomplete in jupyter notebook.
