Q1:Build a phone book program that receives the phone number (Use Input to let the user provide the number), and returns the name of the owner.

You can follow the table below:

Name	Number
Amal	0568323222
Mohammed	0522222232
Khadijah	0532335983
Abdullah	0545341144
Rawan	0545534556
Faisal	0560664566
Layla	0567917077

• If the number exists, print the owner. Otherwise, print "Sorry, the number is not found".
• If the number is less or more than 10 numbers, print "This is invalid number".
• If the number contains letters or symbols, print "This is invalid number".

Exercise: Weather Data Aggregation

Objective: Write a Python program that aggregates weather data for different cities and provides weather data based on user queries.

Requirements:

1. Input Weather Data: Allow the user to input weather data for different cities. Each entry should include the city name, date, temperature, humidity, and weather condition (e.g., sunny, rainy).
2. Store Data in a Dictionary: Use a nested dictionary to store the weather data. The outer dictionary's keys will be the city names, and the values will be another dictionary containing date and weather details.
3. Query by City: Allow the user to query the weather data by city name, displaying all the recorded weather data for that city.

Guidelines:

• Use nested dictionaries to store the weather data efficiently.
• Implement separate functions for inputting data, querying by city.
• Validate user inputs to ensure correctness.

Challenge:

• Extend the program to allow the user to update or delete weather data for a specific city and date.
