Here is how to count the occurrences of an item in a list in Python.

fruits = ['apple', 'banana', 'orange', 'apple', 'pear', 'apple']

# Count the number of 'apple' in the list
apple_count = fruits.count('apple')
print(apple_count) 

# Count the number of 'banana' in the list
banana_count = fruits.count('banana')
print(banana_count)

# Count the number of 'mango' in the list
mango_count = fruits.count('mango')
print(mango_count) 

3
1
0

To count the occurrences of a list item, you can use the count() method on the list. This method takes the item you want to count as an argument and returns the number of times it appears in the list.

fruits = ['apple', 'banana', 'orange', 'apple', 'pear', 'apple']

# Initialize a counter
counter = 0

# Iterate over the list and count the occurrences of 'apple'
for fruit in fruits:
    if fruit == 'apple':
        counter += 1

print(counter)  # Output: 3
