I am stuck at step 14 of thread shed https://www.codecademy.com/courses/learn-python-3/projects/thread-shed
My code is exactly like the walk through video but I keep getting an attribute error
customers =  sales =  thread_sold =  for transaction in transactions_clean: customers.append(transaction) sales.append(transaction) thread_sold.append(transaction) total_sales = 0 for sale in sales: total_sales += float(sale.strip("$"))
Traceback (most recent call last):
File “script.py”, line 139, in
total_sales += float(sale.strip("$"))
AttributeError: ‘list’ object has no attribute ‘strip’
Can somebody help me understand what I’m doing wrong?
