Finding the indexes of a list-CodePudding

I have the following series and I am supposed to pinpoint with a loop the indices that contain exactly the value 6:

    x=[1, 3, 2, 1, 1, 6, 4, 2]  
results=[]

Upon making my code, however, I am getting the output none. What could be going wrong?

def throwing_6(x):
    for index,throw in enumerate(x):
        if throw==6:
            results.append(index)
    results

indexes = throwing_6([1, 2, 6, 3, 6, 1, 2, 6])
print(indexes)

CodePudding user response：

The results array was not defined in the function, before appending elements to it. Also you forgot to return the results array at the end of the function

def throwing_6(x):
    results = []
    for index,throw in enumerate(x):
        if throw==6:
            results.append(index)
    return results;

indexes = throwing_6([1, 2, 6, 3, 6, 1, 2, 6])
print(indexes)

Upon reading user feedback I found the solution see the code between two stars.

def throwing_6(x):
        for index,throw in enumerate(x):
            if throw==6:
                results.append(index)
        **return results**
    
    indexes = throwing_6([1, 2, 6, 3, 6, 1, 2, 6])
    print(indexes)

You could also use a simple list comprehension with condition as follows:

def throwing_6(x):
    return [i for i, v in enumerate(x) if v == 6]
