Basics of python (Session3) - Variables Continued

Two more rules about variable creation
Illegal variable names
Multi- word variables- Camel case, Snake case
Multiple variable declaration and assigning values in one statement
Assign same value to multiple variables
Output variables
*****************************************************************************
Code used in the session
*****************************************************************************
#Variable names cannot start with a number
#Variable names are case-sensitive. age, AGE, aGe

#Illegal varible names
#2myvar # uses number as the first character
# a-b # the variable name has "-" mark in between
# temp name # there is a space in the variable name
#-abc # starts with "-"

#Multi word variable
# we can declare a multi word variable in two ways
# 1. Camel case- first word stars with small letter and subsequent letters are also small
#From the second word on-words the "1st" letter is capital and the rest of the letters in the word are small
studentNameForPythonCourse = "Rahul"
# 2. Snake case
# we combine the words with underscore and all the characters in the variable name generally are small
student_name_for_python_course = "Amit"


# *************************************************************************************************
# Assign multiple values
# *************************************************************************************************
a = 2
b = 4
c = 8

print("Values of the variables: a, b, c", a, b, c)

# the number of variables should be equal to the number of values in the right hand side of the assignment operator
print("New variable values")
a, b, c = 12 , 14, 18
print("Values of the variables: a, b, c", a, b, c)

#Assign same value to many variables
print("The city of the students: ")
a = b = c = "Kolkata"
print("Values of the variables: a, b, c = ", a, b, c)

# *************************************************************************************************
# Output variables
# *************************************************************************************************
x = "Python"
y = "Basics"
print("I am learning "+ x +" " + y)
c = x + " " + y
print(c)

print("Addition of a and b")
a = 10
b = 20
print(a + b)
print("Combine string with value")
a = 32
name = "Ashok"
print("Age of "+name +" is "+ str(a))
