To check if a value exists in a dictionary in Python, you can use the `in` keyword with the dictionary's `values()` method. This allows you to check for the presence of a value in a dictionary.
We can check if a value exists in a dictionary in Python using the `in` keyword with the `values()` method. This example demonstrates how to check for the presence of a value and print a message based on the result.
For example,
my_dict
with integer keys and string values.my_dict = {
1: 'One',
2: 'Two',
3: 'Three'
}
# Value to check
value_to_check = 'Two'
# Check if the value exists using the in keyword
if value_to_check in my_dict.values():
print(f"Value '{value_to_check}' exists in the dictionary.")
else:
print(f"Value '{value_to_check}' does not exist in the dictionary.")
Value 'Two' exists in the dictionary.
We can check if a value does not exist in a dictionary in Python using the `in` keyword with the `values()` method. This example demonstrates how to check for the absence of a value and print a message based on the result.
For example,
my_dict
with integer keys and string values.my_dict = {
1: 'One',
2: 'Two',
3: 'Three'
}
# Value to check
value_to_check = 'Four'
# Check if the value does not exist using the in keyword
if value_to_check not in my_dict.values():
print(f"Value '{value_to_check}' does not exist in the dictionary.")
else:
print(f"Value '{value_to_check}' exists in the dictionary.")
Value 'Four' does not exist in the dictionary.
In this tutorial, we learned How to Check if a Value Exists in a Dictionary in Python language with well detailed examples.
