How to Count True Values in Python?

To count the number of `True` values in Python, you can use any of the following approaches:

1. Using the `count()` method of a list:
``````my_list = [True, False, True, True, False, True, False]
count = my_list.count(True)
print(count)  # Output: 4``````

In this approach, we use the `count()` method of a list, which returns the number of occurrences of a particular value. We pass `True` as the argument to `count()` to count the number of `True` values in the list.

1. Using a loop:
``````my_list = [True, False, True, True, False, True, False]
count = 0
for value in my_list:
if value == True:
count += 1
print(count)  # Output: 4``````

In this approach, we use a loop to iterate through the list and manually count the number of `True` values by checking if each value is equal to `True` using an `if` statement, and incrementing the count if the condition is met.

1. Using the `sum()` function with a list comprehension:
``````my_list = [True, False, True, True, False, True, False]
count = sum([1 for value in my_list if value == True])
print(count)  # Output: 4``````

In this approach, we use a list comprehension to create a list of `1`s for each occurrence of `True` in the original list. Then, we use the `sum()` function to add up all the `1`s, which gives us the count of `True` values in the list.
