# A list comprehnsion is a for loop on a single line
# To create a list comprehension, swap the two lines in the for loop.
# Here we use PyBIDS to extract the relative path for each file:
for fmri in fmri_078:
print(fmri.relpath)
# And here is the equivalent statement as a list comprehension.
# It must be enclosed in square brackets.
# It swaps the order of the lines and loses the colon and indentation
[ print(fmri.relpath) for fmri in fmri_078 ]
