How to turn an string into an integer?
<p>I am doing a little code for my programming class and we need to make a program that calculates the cost of building a desk. I need help changing my DrawerAmount to an integer, not a string!</p>

<pre><code>def Drawers():
print("How many drawers are there?")
DrawerAmount = input(int)
print("Okay, I accept that the total amount of drawers is " + DrawerAmount + ".")
return DrawerAmount

def Desk():
    print("What type of wood is your desk?")
    DeskType = input()
    print("Alright, your desk is made of " + DeskType + ".")
    return DeskType

def Calculation(DrawerAmount, DeskType):
    if "m" in DeskType:
        FinalPrice = DrawerAmount * 30 + 180
    elif "o" in DeskType:
        FinalPrice = DrawerAmount * 30 + 140
    elif "p" in DeskType:
        FinalPrice = DrawerAmount * 30 + 100

def Total():
    print("The final price is " + FinalPrice )

DrawerAmount = Drawers()
DeskType = Desk()
Calculation(DrawerAmount, DeskType)
FinalPrice = Total()
</code></pre>

<pre><code>def Drawers():
    draweramount = input("How many drawers are there?")
    print("Okay, I accept that the total amount of drawers is " + draweramount +     ".")
    return int(draweramount)

def Desk():
    desktype = input("What type of wood is your desk?")
    print("Alright, your desk is made of " + desktype + ".")
    return desktype

def Calculation(draweramount, desktype):
    if "m" in desktype:
        finalprice = draweramount * 30 + 180
    elif "o" in desktype:
        finalprice = draweramount * 30 + 140
    elif "p" in desktype:
        finalprice = draweramount * 30 + 100
    return finalprice

draweramount = Drawers()
desktype = Desk()
finalprice=Calculation(draweramount, desktype)
print("The final price is ",Calculation(draweramount,desktype) )
</code></pre>

<blockquote>
  <p>You haven't specified the output in case the input is not "P" or "M" or "O". 
  Have your functions in small letters and include <strong>_</strong> whenever its a combination of two or more words
  eg. function_name() </p>
