Hi,

I want to change an item from one value to another. How would I do this?

Here is a way

# python 2 and 3

def swap(a, i, j):
    "swap items i and j in the list a"
    a[i], a[j] = a[j], a[i]

if __name__ == "__main__":
    L = list(range(0, 70, 10))
    assert( L == [0, 10, 20, 30, 40, 50, 60] )
    swap(L, 1, 4)
    assert( L == [0, 40, 20, 30, 10, 50, 60] )
    print("success: the swap function worked")
    
""" --> my output
success: the swap function worked
"""

Please, post code in this forum to illustrate your questions.
