connect two dicts in python

To connect or merge two dictionaries in Python, there are several ways to achieve the same outcome. One way to do this is to use the update() method or the ** unpacking operator.

Here's an example using the update() method:

main.py
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}

# update dict1 with the items in dict2
dict1.update(dict2)

print(dict1)
# Output: {'a': 1, 'b': 2, 'c': 3, 'd': 4}
167 chars
9 lines

In the code above, we first define two dictionaries dict1 and dict2. Then we use the update() method on dict1 to append the items in dict2 to dict1.

Another way of merging two dictionaries in Python is by using the ** unpacking operator. As shown below:

main.py
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}

# merge dict1 and dict2 into dict3
dict3 = {**dict1, **dict2}

print(dict3)
# Output: {'a': 1, 'b': 2, 'c': 3, 'd': 4}
170 chars
9 lines

In this code above, we define dict1 and dict2, then we use the ** unpacking operator to merge them into dict3. The operator ** unpacks the items in each dictionary into a new dictionary named dict3.
