# Practice questions on Your class?

## Level 1

1.
Create a Cricle class and intialize it with radius. Make two methods getArea and getCircumference inside this class.
```class Circle():
def  getArea(self):
def getCircumference(self):
```

2.
Create a Temprature class. Make two methods :
1. convertFahrenheit - It will take celsius and will print it into Fahrenheit.
2. convertCelsius - It will take Fahrenheit and will convert it into Celsius.
```class Temprature():
def  convertFahrenhiet(self,celsius):
return (celsius*(9/5))+32
def convertCelsius(self,farenhiet):
return (farenhiet-32)*(5/9)
```

3.
Create a Student class and initialize it with name and roll number. Make methods to :
1. Display - It should display all informations of the student.
2. setAge - It should assign age to student
3. setMarks - It should assign marks to the student.
```class Student():
def __init__(self,name,roll):
self.name = name
self.roll= roll
def display(self):
print self.name
print self.roll
def setAge(self,age):
self.age=age
def setMarks(self,marks):
self.marks = marks
```

4.
Create a Time class and initialize it with hours and minutes.
1. Make a method addTime which should take two time object and add them. E.g.- (2 hour and 50 min)+(1 hr and 20 min) is (4 hr and 10 min)
2. Make a method displayTime which should print the time.
3. Make a method DisplayMinute which should display the total minutes in the Time. E.g.- (1 hr 2 min) should display 62 minute.
```class Time():

def __init__(self, hours, mins):
self.hours = hours
self.mins = mins

t3 = Time(0,0)
if t1.mins+t2.mins > 60:
t3.hours = (t1.mins+t2.mins)/60
t3.hours = t3.hours+t1.hours+t2.hours
t3.mins = (t1.mins+t2.mins)-(((t1.mins+t2.mins)/60)*60)
return t3

def displayTime(self):
print "Time is",self.hours,"hours and",self.mins,"minutes."

def displayMinute(self):
print (self.hours*60)+self.mins

a = Time(2,50)
b = Time(1,20)
