🎓 Welcome back to Digital Academy, the Complete Python Development Tutorial for Beginners, which will help you Learn Python from A to Z!
🖥️ Check if Item Exists in a Dictionary in Python (IN, NOT IN)
If you want to know if a key or values exists inside a dictionary, use the "in" and "not in" Operators in Python, combined with IF statements.
○ Check if Key inside Dictionary
You can use keys() method, to check whether your key is part of the dictionary's keys.
my_dict = {
'age': 27,
'job': 'Youtuber',
'name': 'Digital Academy'
}
print('name' in my_dict) # True
print('salary' in my_dict) # False
print('name' in my_dict.keys()) # True
○ Check if Value inside Dictionary
On the other hand, to check whether a certain value exists inside a dictionary, you must use the "in" operator combined with the values() method.
my_dict = {
'age': 27,
'job': 'Youtuber',
'name': 'Digital Academy'
}
print('Digital Academy' in my_dict.values()) # True
print('Jérémy' in my_dict.values()) # False
