A weather station collects data on temperature, humidity, wind speed, and precipitation. The station needs to issue warnings based on the following criteria: a "high temperature" warning if the temperature is above 35°C and the humidity is above 70%, or a "strong wind" warning if the wind speed is above 60 km/h and there is precipitation.
The program should do the following:
1.
Question
Ask the user to input the temperature in Celsius, humidity as a percentage, wind speed in km/h, and if it's raining (Yes or No).
If elif else statement - Ex01
Save the file as "XX_YYYY_Ex01.py"
2.
Show "It's very hot and humid!" if the temperature is over 35°C and the humidity is over 70%, "It's very windy and rainy!" if the wind speed is over 60 km/h and it's raining, or "No warnings needed." if none of these conditions are met.
3.
Make sure the user enters the right type of data: numbers for temperature, humidity, and wind speed, and Yes or No for raining.
4.
Add notes in the code to explain what it does and what each variable means.

A secondary school is organizing a science fair and needs to determine which students can participate. A student is allowed to participate if they meet the following requirements:
1.
Question
The student is in either Form 5 or Form 6.
If elif else statement - Ex02
Save the file as "XX_YYYY_Ex02.py"
2.
The student has a science grade average of 85 or higher.
3.
The student has either participated in at least 2 science extracurricular activities or has won a science award in the past year.
Write a Python program that checks if a student is eligible to participate in the science fair based on these criteria. The input from user should take in the following information:
1.
The student's level (an integer)
2.
The student's science grade average (an integer)
3.
The number of science extracurricular activities the student has participated in (an integer)
4.
Whether the student has won a science award in the past year (a boolean)
