python list comprehension
# 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)List Comprehensions
numbers = [1, 2, 3, 4, 5, 6]
squares = [i*i for i in numbers]
print(squares)list comprehensions
S = [x**2 for x in range(10)]
V = [2**i for i in range(13)]List Comprehensions in python

In general,
[f(x) if condition else g(x) for x in sequence]
And, for list comprehensions with if conditions only,
[f(x) for x in sequence if condition]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
