# List comprehension example
list = [0 for i in range(10)]
# Makes a list of 10 zeros (Change 0 for different result
# and range for different length)

# Nested List
list = [[0] * 5 for i in range(10)]
# Makes a nested list of 10 list containing 5 zeros (You can also change
# all of the int to produce different results)

Python list comprehension

 # 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 ]
