how to use if statement to choose from three choices

[broception]

I'm trying to get the user to enter what shift they worked, if they enter first shift then the pay rate would be 12.30, if they enter second shift pay rate is 14, and so on.
What I have so far:

firstShift=12.30
secondShift=14.20
thirdShift=15.30
tax = .28
otMultiplier = .5
    
def main():    
    name = getName()
    hrsWrkd = int(input("Enter hours worked: "))
    shift = getShift()
    payRate = getPayRate(shift)
    display(name,shift)

def getName():
    name=input("Enter employee name: ")
    return name
    
def getShift():
    shift = input("Enter shift worked: ")
    return shift

def getPayRate(shift):
    payRate = firstShift
    if shift==firstShift:
        return shift
    if shift==secondShift:
        return 

    
def display(name,shift):
    print("The pay rate for", name)
    print("Working shift",shift,"is",payRate)

main()

The part I need help with is the getPayRate part, I'm not sure how choose from the three work shifts.

I would use a dictionary to contain the pay rates, and return the rate or None which would indicate an invalid answer.

dd = {'first':12.3, 'second':14.0, 'third': 15.3}

def getPayRate(shift):
    return dd.get(shift.lower(), None)

print getPayRate('THIRD')
print getPayRate('xxx')
