Help: for loop with dictionary and nested lists

[mart79]

Hi all,

Can you help me with the following double for loop, writing it more cleanly and make it work for 'lc3'

old = 'car'
new = 'scooter'

loadcases = {'lc1': [['car', 'red', '10'], ['train', 'blue', '20'], ['airplane', 'gray', '300']], 'lc2': [['bike', 'red', '10'], ['train', 'blue', '20'], ['car', 'gray', '300']], 'lc3': 'car'}

# this works for lc1 and lc2 but not for lc3, how can I incorporate this too?
for lc in loadcases:
    for element in loadcases[lc]:
        if element[0] == old:
           element[0] = new

The output needs to be as follows:

Output:
{'lc1': [['scooter', 'red', '10'], ['train', 'blue', '20'], ['airplane', 'gray', '300']], 'lc2': [['bike', 'red', '10'], ['train', 'blue', '20'], ['scooter', 'gray', '300']], 'lc3': 'scooter'}
