Question

Python
-------------------------

### Description

In this exercise, you will add to your `Battery` class
a method to drain the battery.

### Class Name

`Battery`

### Method

`drain()`

### Parameters

* `self` : the `Battery` object to use
* `milliamps` : a number, the amount of charge to remove from the battery.

### Action

Removes `milliamps` from the charge of the object. If the
new charge is less than 0, then set the charge to 0.

Only do this action of `milliamps` is positive, and
the `Battery` isn't already at 0 charge.

### Return Value

`True` if a change occurred, `False` otherwise.

class Battery:
def __init__(self, capacity):
self.capacity = capacity
  
def getCapacity(self):
return self.capacity
  
def getCharge(self):
return self.capacity
  
def drain(self, milliamps):
self.milliamps = milliamps
if self.capacity < 0:
return False
else:
return True

Answer 1

I have completed your class, there was one variable missing, charge , which I added. I have also added some statements to test

class Battery:
  def __init__(self, capacity, charge):
    self.capacity = capacity
    self.charge = charge
  
  def getCapacity(self):
    return self.capacity
  
  def getCharge(self):
    return self.charge
  
  def drain(self, milliamps):
    if milliamps > 0 and self.charge != 0:
      self.charge = self.charge - milliamps
      if self.charge < 0:
        self.charge = 0
      return True
    else:
      return False


b = Battery(20, 18)
print("Current Charge:", b.charge)
b.drain(10)
print("After draining 10 milliamps, Charge:", b.charge)
