1. What is an Assignment Operator?<\/h2>\n

An assignment operator<\/strong> is used to give a value to a variable<\/strong>.<\/p>\n

In simple words:
\ud83d\udc49 It puts a value inside a variable<\/strong>.<\/p>\n

2. Simple Assignment (=<\/code>)<\/h2>\n

The most common assignment operator is =<\/code>.<\/p>\n

Example<\/h3>\n
\n
\n
\n
<\/div>\n<\/div>\n<\/div>\n
x = 10<\/span>
\ny = 5<\/span>
\n<\/code><\/div>\n<\/div>\n

Here:<\/p>\n

    \n
  • \n

    x<\/code> gets value 10<\/code><\/p>\n<\/li>\n

  • \n

    y<\/code> gets value 5<\/code><\/p>\n<\/li>\n<\/ul>\n

    3. Add and Assign (+=<\/code>)<\/h2>\n

    Adds a value and stores the result in the same variable.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 10<\/span>
    \nx += 5<\/span>
    \nprint<\/span>(x)
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    15
    \n<\/code><\/div>\n<\/div>\n

    This is the same as:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = x + 5<\/span>
    \n<\/code><\/div>\n<\/div>\n

    4. Subtract and Assign (-=<\/code>)<\/h2>\n

    Subtracts a value and stores the result.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 10<\/span>
    \nx -= 3<\/span>
    \nprint<\/span>(x)
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    7
    \n<\/code><\/div>\n<\/div>\n

    5. Multiply and Assign (*=<\/code>)<\/h2>\n

    Multiplies and stores the result.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 4<\/span>
    \nx *= 2<\/span>
    \nprint<\/span>(x)
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    8
    \n<\/code><\/div>\n<\/div>\n

    6. Divide and Assign (\/=<\/code>)<\/h2>\n

    Divides and stores the result.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 10<\/span>
    \nx \/= 2<\/span>
    \nprint<\/span>(x)
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    5.0
    \n<\/code><\/div>\n<\/div>\n

    7. Modulus and Assign (%=<\/code>)<\/h2>\n

    Stores the remainder.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 10<\/span>
    \nx %= 3<\/span>
    \nprint<\/span>(x)
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    1
    \n<\/code><\/div>\n<\/div>\n

    8. Power and Assign (**=<\/code>)<\/h2>\n

    Raises power and stores result.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 2<\/span>
    \nx **= 3<\/span>
    \nprint<\/span>(x)
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    8
    \n<\/code><\/div>\n<\/div>\n

    9. Floor Divide and Assign (\/\/=<\/code>)<\/h2>\n

    Divides and removes decimal part.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 10<\/span>
    \nx \/\/= 3<\/span>
    \nprint<\/span>(x)
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    3
    \n<\/code><\/div>\n<\/div>\n

    10. Assignment Operators with Real Example<\/h2>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    \n

    total = 100<\/span><\/code><\/p>\n

    total += 50<\/span>
    \ntotal -= 20<\/span>
    \ntotal *= 2<\/span><\/p>\n

    print<\/span>(total)<\/p>\n<\/div>\n<\/div>\n

    11. Common Beginner Mistakes<\/h2>\n

    \u274c Forgetting to Initialize Variable<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x += 5<\/span>
    \n<\/code><\/div>\n<\/div>\n

    \u274c Error: variable not defined.<\/p>\n

    \u2714 Correct:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 0<\/span>
    \nx += 5<\/span>
    \n<\/code><\/div>\n<\/div>\n

    \u274c Confusing =<\/code> and ==<\/code><\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    if<\/span> x = 5<\/span>:
    \n<\/code><\/div>\n<\/div>\n

    \u2714 Correct:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    if<\/span> x == 5<\/span>:
    \n<\/code><\/div>\n<\/div>\n

    12. Simple Practice Examples<\/h2>\n

    Example 1: Increase Score<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    score = 10<\/span>
    \nscore += 5<\/span>
    \nprint<\/span>(score)
    \n<\/code><\/div>\n<\/div>\n

    Example 2: Reduce Balance<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    balance = 1000<\/span>
    \nbalance -= 250<\/span>
    \nprint<\/span>(balance)
    \n<\/code><\/div>\n<\/div>\n

    Example 3: Square Number<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    num = 4<\/span>
    \nnum **= 2<\/span>
    \nprint<\/span>(num)
    \n<\/code><\/div>\n<\/div>\n

    13. Summary (Assignment Operators)<\/h2>\n

    \u2714 Assignment operators store values
    \u2714 =<\/code> assigns value
    \u2714 += -= *= \/=<\/code> update value
    \u2714 Makes code shorter and cleaner<\/p>\n
