# Functions- Basic Assignments
1. Create a non-return type function that takes the user's name and display the message\
"Hello user! Welcome to Python Functions"
Solution
```python
def greeting(user_name):
print('Hello',user_name,'!Welcome to Python Functions')
name=input('Enter your name:')
greeting(name)
```
2. Create a non-return type function that takes the details of user like name,age, city, company, and profile and display the message-\
"Hello Python, I am name. I am age years old. I am a profile in company"
Solution
```python
def introduction(user_name,user_age,user_profile,user_company):
print('Hello Python, I am',user_name,'.I am',user_age,'years old. I am a',user_profile,'in',user_company,'.')
name=input('Enter your name:')
age=int(input('Enter your age:'))
profile=input('Enter Your profile:')
company=input('Enter your company:')
introduction(name,age,profile,company)
```
3. Create a return type function that takes the length and breadth of a rectangle and calculate area of the rectangle.
Solution
```python
def area_of_rectangle(length,breadth):
area=length * breadth
return area
length=int(input('Length of the rectangle:'))
breadth=int(input('breadth of the rectangle:'))
print('Area of the rectangle is ',area_of_rectangle(length,breadth))
```
4. Create a return type function that takes weight and height of a user and return the bmi of the user.\
Depending upon the bmi show the category that the custimer belongs to.
Solution
```python
def calculate_BMI(weight,height):
bmi=round(weight / height ** 2 * 10000)
return bmi
w=int(input('enter Weight:'))
h=int(input('enter height:'))
bmi=calculate_BMI(w,h)
print('Your BMI is:',bmi)
print('Your Category:')
print('Underweight:',bmi<18.5)
print('Normal range:',bmi>=18.5 and bmi<=24.9)
print('Overweight:',bmi>=25.0 and bmi<=29.9)
print('Obese:',bmi>=30)
```
5. Create a return type function that takes principle, rate, and time from the user and then return simple interest after calculation.Afterwards Calculate amount that the user has to repay.
Solution
```python
def calculate_simple_interest(principle,rate,time):
simple_interest=principle * rate * time / 100
return simple_interest
principle=int(input('Enter principle:'))
rate=int(input('Enter Rate:'))
time=int(input('Enter time:'))
si=calculate_simple_interest(principle,rate,time)
print('Your interest charged will be:',si)
amount=principle + si
print('Amount you will repay is',amount,'Rs')
```
6. Create a return function that takes the radius and height of a cylinder and return the total surface area.\
TSA = 2πr\*(r + h).
Solution
```python
def total_surface_area_cylinder(radius,height,pi=3.14):
total_surface_area = 2 * pi * radius *(radius + height)
return total_surface_area
radius= int(input('Enter radius of the cylinder:'))
height= int(input('Enter height of the cylinder:'))
print('the total surface area of the cylinder is',total_surface_area_cylinder(radius,height))
```
7. Create a function that takes the radius and height of a cone and return the volume.\
V=1/3hπr²
Solution
```python
def volume_of_cone(radius,height,pi=3.14):
volume = (pi * radius ** 2 * height) * 1 / 3
return volume
radius= int(input('Enter radius of the cone:'))
height= int(input('Enter height of the cone:'))
v= volume_of_cone(radius,height)
print('Volumeof the cone',v)
```
8. Create a function that returns the quotient and remainder after dividing two numbers.
Solution
```python
def calculate_quotient_remainder(num1,num2):
res1=num1//num2
res2=num1%num2
return res1,res2
a=int(input('enter first number:'))
b=int(input('enter second number:'))
quot,rem=calculate_quotient_remainder(a,b)
print('quotient:',quot)
print('remainder:',rem)
```
9. Create a return type function that takes marks of 5 subjects from a student and calculates the percentage of the student.
Solution
```python
def percentage(m1,m2,m3,m4,m5):
sum=m1+m2+m3+m4+m5
percent= sum * 100/500
return percent
phys=int(input('Enter Physics marks:'))
chem=int(input('Enter chemistry marks:'))
maths=int(input('Enter maths marks:'))
hindi=int(input('Enter hindi marks:'))
english=int(input('Enter english marks:'))
per=percentage(phys,chem,maths,hindi,english)
print('Your percentage is:',per,'%')
```
10. Create a function called create\_bill that takes product name,price, and qty and return the bill.
Solution
```python
def create_bill(product_name,product_price,product_qty):
bill=product_price * product_qty
return bill
product=input('enter name of the product:')
price=int(input('enter price:'))
quantity=int(input('Enter quantity:'))
amount=create_bill(product,price,quantity)
print('The bill of',product,'of',price,'Rs for',quantity,'pieces is Rs',amount)
```
