Problem:

Hello, experts.

I am a new Python learner. I’ve been learning computer programming since last week. I am learning new things every single day. Today, I have got a problem when working with a python dictionary. I’ve created a Python dictionary. For example:

a = {'Name':'Steve', 'Age':30, 'Designation':'Programmer'}

is my dictionary. Now, my question is, how I am gonna find how many elements are available in my dictionary while I need to use the dictionary in my program? My question might be sounds silly to you, but it needs to be answered badly. I am looking forward to hearing from you, mate. Thanks for your kind help

Solution:

In Python. dictionaries are the collection of mixed values. As far as your given dictionary is concerned, it is holding the key-value pairs of data in it. In your question, you are asking to get the length of a dictionary. Python has many built-in functions. One of the most popular and widely used functions is .len() function. To get the length you can use the len() function. This way:

a = {'Name':'Steve', 'Age':30, 'Designation':'Programmer'}
print(len(a))
