Hi I tried writing a nested loop instead of using the zip function. But I am getting an error. Can you please help me in finding what am I doing wrong? companies = ['Python DS', 'PythonSoft', 'Pythazon', 'Pybook'] key_name = ['open', 'high', 'low', 'close'] prices = [[12.87, 13.23, 11.42, 13.10],[23.54,25.76,21.87,22.33], [98.99,102.34,97.21,100.065],[203.63,207.54,202.43,205.24]] share_prices = dict() for i in range(4): for j in range(4): share_prices[companies[i]][key_name[j]]=prices[i][j] print(share_prices) I am getting a key error: KeyError: 'Python DS'

Hey Nirmal, Thank you for your question! Below, I provide an example solution to the problem. First, a temporary dictionary is defined, called temp_dict, which serves as the value of each key in the share_prices dictionary. The key of temp_dict is key_name[j] while its value is prices[i][j]. At the end of the first loop, we assign temp_dict as the value of share_prices[companies[i]]. Hope this helps! Kind regards, 365 Hristina
