Important Points When Assigning Values to Variables

In programming, assignment refers to the process of storing a specific value in a declared variable.

For example, x = 5 means that the value 5 is stored in the variable x.

In the previous lesson, initialization refers to the process of assigning values to a declared variable.


Important Notice​

In programming, the = symbol does not mean "equals" as in mathematics, but rather means assign the value on the right to the variable on the left.

Example of Variable Assignment
number = 10

message = "Hello, Python!"

In the code above, number = 10 means assigning the number 10 to the variable number.

Similarly, message = "Hello, Python!" assigns the string "Hello, Python!" to the variable message.

When using an equal sign to mean "equals," use two equal signs as in ==.

Using Equal Sign to Mean 'Equals'
if number == 10:
    print("number is 10.")

Variable Reassignment​

In Python, you can assign a new value to an already assigned variable.

In this case, the previous value is replaced with the reassigned value.

Example of Variable Reassignment
number = 10  # Assign the value 10 to the variable number

number = 15  # Reassign the new value 15 to number, which was initially 10

Multiple Assignment​

In Python, you can assign values to multiple variables simultaneously in one line.

Example of Multiple Assignment
x, y, z = 5, 10, 15

print(x)  # 5

print(y)  # 10

print(z)  # 15

Coding Practice​

Try reassigning the value of the variable student_name.
