[Python] Creating a calculator python

I am fairly new to python and programming in general, I wanted to build a calculator which could handle multiple operations in a equation. I implemented multiplication and division, however an index out of range error occurs ONLY when a division comes after a multiplication.

Code

def find(s, ch):
return [i for i, ltr in enumerate(s) if ltr == ch]

operatorList=["+","-","%","x","/"]
userInput=input("Please enter an equation: ")
newInput=("")
operatorsUsedList=[]
for char in userInput:
if char in operatorList:
userInput=userInput.replace(char,',')
operatorsUsedList.append(char)
print(userInput)
print(operatorsUsedList)
listOfNums=userInput.split(",")
print(listOfNums)
divIndex=find(operatorsUsedList,"/")
multiIndex=find(operatorsUsedList,"x")
print(divIndex)
#Makes str into nums
count=0
listOfNums = [int(i) for i in listOfNums]
while len(listOfNums)!=1:
count=0
for i in divIndex:
inputA=listOfNums[i-count]
inputB=listOfNums[i+1-count]
print(inputA,"/",inputB)
print("here")
result=inputA/inputB
try:
del listOfNums[i+1-count]
except:
pass
try:
del listOfNums[i-count]
except:
pass
listOfNums.insert(i,result)
print(listOfNums)
count=count+1
for i in multiIndex:
inputA=listOfNums[i-count]
inputB=listOfNums[i+1-count]
print(inputA,"x",inputB)
print("here")
result=inputA*inputB
try:
del listOfNums[i+1-count]
except:
pass
try:

del listOfNums[i-count]
except:
pass

listOfNums.insert(i,result)
print(listOfNums)
count=count+1

print("Answer = ",str(listOfNums))


Results

When i input 6/3/2x4 I am returned Answer = [4.0] which is correct.

However when i input 4x2/3/6 its returning IndexError. Here is the traceback,

Traceback (most recent call last):
File "xxxxx.py", line 26, in <module>
inputB=listOfNums[i+1-count]
IndexError: list index out of range


Any help is appreciated
