How to compare and lookup one list with another list?

Question

I have 2 lists – one holds `int values and the other string. I am iterating through the list to find the highest value in it and once I do I want to lookup the corresponding name for that highest value. I am reading my data from a csv file that has 2 columns: month and amount.

monthSales = []
totalSales = []

for col in sale:
    monthSales.append(col['month'])
    totalSales.append((col['sales']))
print('Month: ', monthSales)
print('Sales: ', totalSales)
print(max(totalSales))
print(min(totalSales))

this gives the following output

Month:  ['jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'oct', 'nov', 'dec']
Sales:  ['6226', '1521', '1842', '2051', '1728', '2138', '7479', '4434', '3615', '5472', '7224', '1812']

I can get the highest and lowest values using max and min but I want to be able to extract the associated month with it and display that along with the value.

so for example using above: highest sales is 7479 which is in month July. so how do i display both this values?

any help appreciated

I have managed to get max and min sales but just need guidance on how to do a secondary lookup for the corresponding list associated with the sales list

You could just make one list of tuples, and then call max or min with the key argument to use the sales number:

sales = [(col['month'], int(col['sales'])) for col in sale]
print(max(sales, key=lambda x: x[1]))
print(min(sales, key=lambda x: x[1]))
