Declare a string a variable in python

Question

My code has variables mri1_tasks and mri2_tasks. Is there a function to have python interpret 'mri%d_tasks'%num (where num is equal to either 1 or 2) as the stored value of mri1_tasks or mri2_tasks based on the value of num?

Is there any reason you can't use a list with both strings at separate indices and use the index as the switch? — J. da Silva, Sep 30 '15 at 19:10

Instead of having two variables, you can store the variables in a dictionary, with variable name as the key.

vars = {
    'mri1_tasks': 0,
    'mri2_tasks': 1,
}

num = 1
print vars['mri%d_tasks'%num]
