Docs:
"""
Given format % values (where format is a string or Unicode object), %
conversion specifications in format are replaced with zero or more
elements of values. [snip]
If format requires a single argument, values may be a single non-tuple
object. [snip] Otherwise, values must be a tuple with exactly the
number of items specified by the format string, or a single mapping
object (for example, a dictionary).
"""

# so you obtain a list somehow
alist = ['01', '02', '03', '04', '05']
# and much later you need to format the contents
formatted = '%s %s %s %s %s' % tuple(alist)
