How to create tuple with a loop in python

Question

I want to create this tuple:

a=(1,1,1),(2,2,2),(3,3,3),(4,4,4),(5,5,5),(6,6,6),(7,7,7),(8,8,8),(9,9,9)

I tried with this

a=1,1,         


        

Answer 1

A tuple is an immutable list. This means that, once you create a tuple, it cannot be modified. Read more about tuples and other sequential data types here.

So, if you really need to change a tuple during run time:

1. Convert the tuple into a list
2. Make the necessary changes to the list
3. Convert the list back to a tuple

or

1. Create a list
2. Modify the list
3. Convert the list into a tuple

So, in your case:

a = []
for i in range (1,10):
    a.append((i,i,i))
a = tuple(a)   
print a
