# User Input & Type Casting
1. **Take the name from the user and greet him in this form - Hello, username**
Solution
```python
name = input('Enter Your Name : ')
print('Hello,', name)
```
2. **`Take input of the length and breadth of a rectangle from the user and print the area of it.`**
Solution
`length = float(input('Enter the length : '))`
`breadth = float(input('Enter the breadth : '))`
`area = length * breadth`
`print('Area :', area)`
3. **`Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. The Table below shows how healthy you are with respect to your BMI.`**
**`The Formula That we use For BMI is :`**
$$
bmi = weight(kgs)/height(cms)^2\*10000
$$
**`Take Weight and height from the user and Calculate BMI.`**
Solution
**First we will take weight and height from user with the help of user input.**
`weight = int(input('Enter your weight : '))`
`height = int(input('Enter your height : '))`
**Then we will calculate BMI , Now say if we want only two decimal values , we can use `round()` Function.**
`bmi = round(weight / height ** 2 * 10000)`
`print('Your BMI is',bmi)`
*4.* **`Take Principle, Rate, and Time From User and Calculate Simple Interest.`**
**`Formula For Simple Interest is:`**
$$
Simple Interest = Principle \* Rate \* Time / 100
$$
Solution
`principle = int(input('Enter the amount : '))`
`rate = int(input('Rate : '))`
`time = int(input('Time : '))`
`simple_interest = principle * rate * time / 100`
`print('Simple Interest is',simple_interest)`
5\. **`Your task is to take name and age and location from user and print the following message :`**
**`Hello Everyone , I am xyz and i am xyz years old and i live in xyz.`**
Solution
`name = input('Enter your name : ')`
`age = input('What is your age ? ')`
`location = input('Where do you live ? ')`
`print('Hello Everyone , I am' ,name, 'and i am', age, 'years old and i live in', location,'.')`
**`6. Suppose there are many N numbers of people in the Army. We need to distribute them in G groups. Take the number of people from users and the Number of Groups and tell how many are left without Group.`**
Solution
`n = int(input('Number of Army People : '))`
`g = int(input('How many groups do we need ? '))`
`rest = n%g`
`print('Remaining People :',rest)`
**`7.Take Temperature in Fahrenheit and convert it into Celsius.`**
**`Formula:` *****C = 5/9 \* ( F - 32 )***
Solution
```python
# Ask user for temperature in Fahrenheit
fahrenheit = float(input("Enter temperature in Fahrenheit: "))
# Convert to Celsius
celsius = (fahrenheit - 32) * 5/9
# Print result
print(fahrenheit,' degrees Fahrenheit is equal to',celsius,'degrees Celsius.")
```
8. Take two variables from user value and power and print the solution value raised to power.\
Such as value = 3 and power = 2 then solution is 9
Solution
```python
value = int(input('Enter the Number : '))
power = int(input('Enter the power : '))
solution = value ** power
print('Solution is', solution)
```
9. Tom had y amount in his bank and jeff withdrew x amount where x is always less than y. Print the remaining balance in Tom's account. Take x and y from the user.
Solution
```python
y = int(input("Enter Tom's account balance : "))
x = int(input('Enter withdrawal amount : '))
balance = y - x
print('Remaining balance :', balance)
```
10. Take the base and height of a triangle from the user and calculate the area of the triangle.\
area=(base \* height)\*1/2
Solution
```python
base=int(input('Enter the base of the triangle:'))
height=int(input('Enter the height of the triangle:'))
area=(base*height)*1/2
print('Area of the triangle is',area)
```
11. **Take 5 numbers from the user and calculate average of those numbers.**
**(average=sum of data/number of data)**
Solution
```python
num1=int(input('Enter first number:'))
num2=int(input('Enter first number:'))
num3=int(input('Enter first number:'))
num4=int(input('Enter first number:'))
num5=int(input('Enter first number:'))
average=(num1+num2+num3+num4+num5)/5
print('Average of the numbers',average)
```
12. Take the sides of a triangle and check whether it follows Pythagoras' theorem.\
sq. of base + sq. of height=sq. of hypotenuse
Solution
```python
base=int(input('Enter base of the triangle:'))
height=int(input('Enter height of the triangle:'))
hypotnuse=int(input('Enter hypotnuse of the triangle:'))
result=base**2 + height **2
print('pythagoras theorem:',result==hypotnuse**2)
```
13. Take the length and breadth of a rectangle and find the perimeter of the rectangle\
perimeter= 2 \* (length + breadth)
Solution
```python
length=int(input('Enter length of the rectangle:'))
breadth=int(input('Enter breadth of the rectangle:'))
perimeter= 2* (length + breadth)
print('Perimeter of the rectangle with sides', length,'and',breadth,' will be', perimeter)
```
14. Take the side of a cube in cm and calculate the volume of the cube.\
volume= side \* side \* side
Solution
```python
side=int(input('Enter side of a cube:')
volume= side ** 3
print('Volume of the cube:',volume,'cubic cm')
```
15. Take the length, breadth, and height of a cuboid in cm and calculate the volume of the cuboid.\
volume= length \* breadth \* height
Solution
```python
length= int(input('Enter length of the cuboid:'))
breadth=int(input('Enter breadth of the cuboid:'))
height= int(input('Enter height of the cuboid:'))
volume= length * breadth * height
print('Volume of the cuboid:',volume,'cubic cm')
```
16. Take the radius and height of a cylinder and calculate the total surface area.\
total\_surface\_area= 2\*3.14\* radius \*height + 2\* 3.14 \* sq. of radius
Solution
```python
radius= int(input('Enter radius of the cylinder:'))
height= int(input('Enter height of the cylinder:'))
pi=3.14
total_surface_area = 2*pi*radius*height + 2*pi*radius**2
print('the total surface area of the cylinder is',total_surface_area)
```
17. Take the radius and height of a cone and calculate the volume of it.\
volume= (3.14 \* sq of radius \* height) \* 1/3
Solution
```python
radius= int(input('Enter radius of the cone:'))
height= int(input('Enter height of the cone:'))
pi=3.14
volume= (pi * radius **2 *height)*1/3
print('Volumeof the cone',volume)
```
18. Take the radius and length of a cone and calculate the total surface area of it.\
total\_surface\_area= 3.14\*radius\*(radius + length)
