## Check if multiple variables are equal in Python#

Use the equality operator to check if multiple variables are equal, e.g. `if a == b == c:`. The expression will compare the variables on the left-hand and right-hand sides of the equal signs and will return `True` if they are equal.

main.py
```Copied!```a = 123
b = 123
c = 123

# ✅ Check if multiple variables are equal to value

if a == b == c == 123:
# 👇️ this runs
print('Variables are equal to value')

# -------------------------------------------------

# ✅ Check if multiple variables are equal

if a == b == c:
# 👇️ this runs
print('Multiple variables are equal')

# -------------------------------------------------

my_list = [a, b, c]

# ✅ Check if multiple variables in a sequence (e.g. list) are equal to value

if all(item == 123 for item in my_list):
# 👇️ this runs
print('Variables are equal to value')

# -------------------------------------------------

# ✅ Check if multiple variables in a sequence (e.g. a list) are equal

if my_list.count(my_list) == len(my_list):
# 👇️ this runs
print('Multiple variables are equal')
``````

We used the equality `==` operator multiple times to check if multiple variables store the same value.

main.py
```Copied!```a = 123
b = 123
c = 123

if a == b == c:
# 👇️ this runs
print('Multiple variables are equal')

# -------------------------------------------------

if a == b == c == 123:
# 👇️ this runs
print('Variables are equal to value')

``````

If the variables store the same value, the expression returns `True`, otherwise `False` is returned.

main.py
```Copied!```a = 123
b = 123
c = 123

are_equal = a == b == c
print(are_equal)  # 👉️ True
``````

If you need to check if multiple variables are equal to a specific value, add another equal sign to the expression and compare to the value.

main.py
```Copied!```a = 123
b = 123
c = 123

are_equal_to_value = a == b == c == 123
print(are_equal_to_value)  # 👉️ True

if a == b == c == 123:
# 👇️ this runs
print('Variables are equal to value')
``````

## Check if multiple variables in a sequence are equal#

To check if multiple variables in a sequence (e.g. list, tuple) are equal:

1. Use the `count()` method to count the occurrences of the first item in the sequence.
2. Compare the count with the length of the sequence.
3. If the two values are equal, all values in the sequence are equal.
main.py
```Copied!```a = 123
b = 123
c = 123

my_list = [a, b, c]

if my_list.count(my_list) == len(my_list):
# 👇️ this runs
print('Multiple variables are equal')
``````

The `list.count()` method takes a value as an argument and returns the number of times the provided value appears in the list.

If the number of times the first item appears in the sequence is the same as the length of the sequence, then all values in the sequence are equal.

Alternatively, you can use a generator expression to check if all values in a sequence are equal.

main.py
```Copied!```a = 123
b = 123
c = 123

my_list = [a, b, c]

if all(item == my_list for item in my_list):
# 👇️ this runs
print('Multiple variables are equal')
``````

We used a generator expression to iterate over the list.

Generator expressions are used to perform some operation for every element, or select a subset of elements that meet a condition.

On each iteration, we check if the current value is equal to the first list element and return the result.

The all() built-in function takes an iterable as an argument and returns `True` if all elements of the iterable are truthy (or the iterable is empty).

## Check if multiple variables in sequence are equal to a value#

To check if multiple variables in a sequence are equal to a value:

1. Use a generator expression to iterate over the sequence.
2. On each iteration, compare the current item to the specific value.
3. Pass the generator object to the `all()` function.
main.py
```Copied!```a = 123
b = 123
c = 123

my_list = [a, b, c]

if all(item == 123 for item in my_list):
# 👇️ this runs
print('Variables are equal to value')
``````

On each iteration, we compare the current list item to a specific value and return the result.

If all of the comparisons evaluate to `True`, the `all()` function will also return `True`.
