I would like to calculate the "size on disk" of a file in Python. Therefore I would like to determine the cluster size of the file system where the file is stored. How do I determine the cluster size in Python? Or another built-in method that calculates the "size on disk" will also work. I looked at os.path.getsize but it returns the ...

I haven’t been able to find a good solution for this problem on the net (probably because switch, position, list and Python are all such overloaded words). It’s rather simple – I have this list: ['title', 'email', 'password2', 'password1', 'first_name', 'last_name', 'next', 'newsletter'] I’d like to switch position of 'password2' and...

How can I efficiently and easily sort a list of tuples without being sensitive to case? For example this: [('a', 'c'), ('A', 'b'), ('a', 'a'), ('a', 5)] Should look like this once sorted: [('a', 5), ('a', 'a'), ('A', 'b'), ('a', 'c')] The regular lexicographic sort will put 'A' before 'a' and yield this: [('A', 'b'), ('a', 5), ('...
