# Python increment by 1

To increment a variable by 1 in Python, you can use the augmented assignment operator `+=`. This operator adds the right operand to the left operand and assigns the result to the left operand. For example, if you have a variable `x` with the value 5, you can increment it by 1 using the following code:

```x += 1
```

After this code is executed, the value of `x` will be 6. You can also use the `+=` operator with other operands, such as strings, lists, and dictionaries. For example, if you have a string `s` with the value “hello”, you can increment it by 1 by appending the character “a” to it:

```s = "hello"
s += "a"
```

After this code is executed, the value of `s` will be “helloa”.

## Incrementing by 1 with List

If you have a list `l` with the elements [1, 2, 3], you can increment it by 1 by appending element 4 to it:

```l = [1, 2, 3]
l += 
```

After this code is executed, the value of `l` will be [1, 2, 3, 4].

## Dictionary increment by 1

Let’s look at another example of incrementing by 1 with a dictionary.

```d = {"a": 1, "b": 2}
d += {"c": 3}
print(d)
```

In this case, the `+=` operator merges the dictionary `d` with the dictionary `{"c": 3}`, resulting in the dictionary {“a”: 1, “b”: 2, “c”: 3}.

Overall, to increment a variable by 1 in Python, you can use the augmented assignment operator `+=`. This operator adds the right operand to the left operand and assigns the result to the left operand, allowing you to increment variables of different types by 1.
