Question

In Python, I am writing a script that will simulate a customer placing an order. It will consist of creating the order, adding lines to it, and then checking out. I am currently doing it with something like:

api = ['login', 'createOrder', 'scanBarCode', 'addLine', 'checkout']
for apiName in apiList:
  #call API

I am designing this more as a framework so it would be easy to add new APIs in case things change. My design question is this: How can I code it so that I can call scanBarCode and addLine N number of times? Something like:

api = ['login', 'createOrder', 'scanBarCode', 'addLine', 'checkout']
numberOfLines = (random number)
for apiName in apiList:
  #call API
  #if API name is scanBarCode, repeat this and the next API numberOfLines times, then continue with the rest of the flow

Something like the following should get you started:

import random
api = ['login', 'createOrder', 'scanBarCode', 'addLine', 'checkout']
numberOfLines = random.randint(1, 10)   # replace 10 with your desired maximum
for apiName in api:
    if apiName == 'scanBarCode':
        for i in range(numberOfLines):
            # call API and addLine
    else:
        # call API
