+# Hi! Welcome to this mini tutorial on using list comprehensions in Python!
+# Check out samplelists.py if you need help with lists.
+
+# Starting off with list comprehensions!
+# Syntax used to make an ordinary list:
+my_list = ["apple", "banana", "pear", "peach"]
+
+# To concisely make a new list of elements, use a list comprehension:
+list_comp = [num for num in range(10)] # Notice how square brackets are
+# used to create a list.
+print list_comp
+
+# List comprehension syntax can be understood as so:
+# [num for num in range(5)]
+# Make a new num for each num in given range
+
+# The first expression (before the "for" keyword) can be altered to satisfy a
+# given condition over an iterable.
+doubled_list_comp = [num * 2 for num in list_comp]
+print doubled_list_comp
+
+# Furthermore, "if" statements can be used in list comprehensions as well.
+even_num_list_comp = [num for num in list_comp if num % 2 == 0]
+print even_num_list_comp
