Python: How do I replace value in a nested list?

Question

How do I replace James's salary from 1000 to 1500 and print James's data?

data = [['Ben', 'Manager', 3000],
           ['James', 'Cleaner', 1000],
           ['Ken', 'Supervisor', 2000]]

for (name,appt,salary) in data:
    if name == 'James':
        salary = 1500
        print(linked_data[1]) 

Here's my current output:

['James', 'Cleaner', 1000]

Expected output:

['James', 'Cleaner', 1500]

Answer 1

You need to find the index at which it occurs. Use enumerate.

for idx, (name,appt,salary) in enumerate(data):
    if name == 'James':
        # salary is at index 2 in the inner list
        data[idx][2] = 1500
        print(f"{name},{appt},{salary}")

Answer 2

If you know the index then you can do:

data = [['Ben', 'Manager', 3000],
           ['James', 'Cleaner', 1000],
           ['Ken', 'Supervisor', 2000]]


data[1][2] = 1500

print(data[1])

output:

['James', 'Cleaner', 1500]
