Convert tuple to list and back

People also ask

Can you convert a tuple to a list?

We can use the list() function to convert tuple to list in Python.

Which method converts a tuple into list?

Python list method list() takes sequence types and converts them to lists. This is used to convert a given tuple into list. Note − Tuple are very similar to lists with only difference that element values of a tuple can not be changed and tuple elements are put between parentheses instead of square bracket.

Can we convert list to tuple and tuple to list in Python?

tuple () function can take any iterable as an argument and convert it into a tuple object. As you wish to convert a python list to a tuple, you can pass the entire list as a parameter within the tuple() function, and it will return the tuple data type as an output.

How do you convert a tuple to an array in Python?

To convert a tuple of lists into an array, use the np. asarray() function and then flatten the array using the flatten() method to convert it into a one-dimensional array.


Convert tuple to list:

>>> t = ('my', 'name', 'is', 'mr', 'tuple')
>>> t
('my', 'name', 'is', 'mr', 'tuple')
>>> list(t)
['my', 'name', 'is', 'mr', 'tuple']

Convert list to tuple:

>>> l = ['my', 'name', 'is', 'mr', 'list']
>>> l
['my', 'name', 'is', 'mr', 'list']
>>> tuple(l)
('my', 'name', 'is', 'mr', 'list')

You have a tuple of tuples.
To convert every tuple to a list:

[list(i) for i in level] # list of lists

--- OR ---

map(list, level)

And after you are done editing, just convert them back:

tuple(tuple(i) for i in edited) # tuple of tuples

--- OR --- (Thanks @jamylak)

tuple(itertools.imap(tuple, edited))

You can also use a numpy array:

>>> a = numpy.array(level1)
>>> a
array([[1, 1, 1, 1, 1, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 0, 0, 0, 0, 1],
       [1, 1, 1, 1, 1, 1]])

For manipulating:

if clicked[0] == 1:
    x = (mousey + cameraY) // 60 # For readability
    y = (mousex + cameraX) // 60 # For readability
    a[x][y] = 1

You can have a list of lists. Convert your tuple of tuples to a list of lists using:

level1 = [list(row) for row in level1]

or

level1 = map(list, level1)

and modify them accordingly.

But a numpy array is cooler.


To convert tuples to list

(Commas were missing between the tuples in the given question, it was added to prevent error message)

Method 1:

level1 = (
     (1,1,1,1,1,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,1,1,1,1,1))

level1 = [list(row) for row in level1]

print(level1)

Method 2:

level1 = map(list,level1)

print(list(level1))

Method 1 took --- 0.0019991397857666016 seconds ---

Method 2 took --- 0.0010001659393310547 seconds ---


Why don't you try converting its type from a tuple to a list and vice versa.

level1 = (
     (1,1,1,1,1,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,0,0,0,0,1)
     (1,1,1,1,1,1))

print(level1)

level1 = list(level1)

print(level1)

level1 = tuple(level1)

print(level1)
