🚀 Day 73/150 – Merge Two Dictionaries in Python

Dictionaries are one of Python’s most useful data structures, and combining two dictionaries is a common task when working with data.

In this post, we'll explore different ways to merge dictionaries in Python.

---

✅ Method 1 – Using update()

The update() method adds all key-value pairs from one dictionary into another.

dict1 = {"name": "John", "age": 20}
dict2 = {"course": "Python", "city": "Delhi"}

dict1.update(dict2)

print(dict1)

Output

{'name': 'John', 'age': 20, 'course': 'Python', 'city': 'Delhi'}

How it works

• update() modifies the original dictionary.
• Existing keys are overwritten if duplicates exist.

---

✅ Method 2 – Using Dictionary Unpacking (**)

Python allows unpacking dictionaries and combining them into a new dictionary.

dict1 = {"name": "John", "age": 20}
dict2 = {"course": "Python", "city": "Delhi"}

result = {**dict1, **dict2}

print(result)





Output

{'name': 'John', 'age': 20, 'course': 'Python', 'city': 'Delhi'}

Why use it?

• Creates a new dictionary.
• Keeps the original dictionaries unchanged.

---

✅ Method 3 – Using the | Operator (Python 3.9+)

Python 3.9 introduced a dedicated merge operator for dictionaries.

dict1 = {"name": "John", "age": 20}
dict2 = {"course": "Python", "city": "Delhi"}

result = dict1 | dict2

print(result)

Output

{'name': 'John', 'age': 20, 'course': 'Python', 'city': 'Delhi'}

Benefits

• Clean and readable syntax.
• Returns a new merged dictionary.

---

✅ Method 4 – User-Defined Dictionaries

You can merge any dictionaries created by the user.

dict1 = {"a": 1, "b": 2}
dict2 = {"c": 3, "d": 4}

merged = {**dict1, **dict2}

print(merged)





Output

{'a': 1, 'b': 2, 'c': 3, 'd': 4}

---

⚠️ What Happens with Duplicate Keys?

dict1 = {"name": "John", "age": 20}
dict2 = {"age": 25, "city": "Delhi"}

result = {**dict1, **dict2}

print(result)

Output

{'name': 'John', 'age': 25, 'city': 'Delhi'}


The value from the second dictionary replaces the value from the first dictionary when keys are the same.

---

🎯 Key Takeaways

✔️ Use update() when you want to modify the existing dictionary.
✔️ Use ** unpacking when you want a new merged dictionary.
✔️ Use | operator for cleaner syntax in Python 3.9+.
✔️ If duplicate keys exist, the last dictionary's value wins.

Python Coding Challenge - Question with Answer (ID -230626)

 

Explanation:

Line 1

clcoding = map(str, [1, 2, 3])

Step 1: List Creation

[1, 2, 3]

A list containing three integers is created:

Index Value

0 1

1 2

2 3

Step 2: str Function

str

str() is a built-in Python function that converts a value into a string.

Examples:

str(1)   # '1'

str(2)   # '2'

str(3)   # '3'

Step 3: map() Function

map(str, [1, 2, 3])

Syntax:

map(function, iterable)

Here:

Function → str

Iterable → [1, 2, 3]

Python will apply str() to every element of the list.

Conceptually:

1 → '1'

2 → '2'

3 → '3'

Result:

['1', '2', '3']

But map() does not create the list immediately.

It creates a map object (iterator).

So:

clcoding

stores:

<map object>

Line 2

print(next(clcoding))

Step 1: next()

next() retrieves the next value from an iterator.

Syntax:

next(iterator)

Since clcoding is a map iterator:

next(clcoding)

fetches the first converted value.

Internally:

1 → str(1) → '1'

Returned value:

'1'

Step 2: print()

print('1')

prints:

1

(Output appears without quotes.)

Output

1
