Python Duplicate Dictionary

Question

I am unable to create a "duplicate" dictionary in the program

below is the sample code

dict1={'name':'rahul',age:30}

i need to create a dictionary with two entries.

`dict2 = dict(dict1)`? or https://docs.python.org/3/library/copy.html?highlight=deepcopy#copy.deepcopy ? https://stackoverflow.com/questions/2465921/how-to-copy-a-dictionary-and-only-edit-the-copy . what have you tried? — hiro protagonist, Mar 02 '20 at 07:24
@sudarshang is `age` a variable referencing a string? I think you might want to put ticks around the word "age". Might be helpful too if you could say what the error message is that you're seeing. — Todd, Mar 02 '20 at 07:59

In Python, there are two ways to create copies :

In order to make these copy, you can use the copy module.
For Example:

import copy 

dict1={'name':'rahul', 'age': 30}   

# Shallow copy   
dict2 = copy.copy(dict1)  

# Deep Copy  
dict3 = copy.deepcopy(dict1)

If you don't know the difference between shallow copy and deep copy please check this very good article: https://docs.roguewave.com/sourcepro/11.1/html/toolsug/6-4.html

I find this image essential in understanding the concept:

You're missing the quotes around age:

dict1={'name':'rahul', 'age':30}

Do you mean copying a dictionary? You have two options:

In python dictionary both key and value should be Enclosed with double Quotes or Single Quotes if the value is a string.

You can't assign a value to a key like assigning value to a variable

Example:

In dictionary you should assign as 'age':30

If 'age' is a variable that you are declaring outside the dictionary then you can assign as

age = 30

Coming back to your Question did you mean copying a dictionary or just create a duplicate like this

dict1={'name':'rahul','age':30} dict2={'name':'rahul','age':30} print(dict1) print(dict2)
