# Normal use of a for loop ...

# without list comprehension
str = "abc"
res = []
for s in str:
res.append(s.capitalize())
assert res == ['A', 'B', 'C']
Comprehension
For loops can be write more concisely using list comprehension.
# List comprehension
#
# The loop variable appears in expression before we get to definition
# List comprehensions are more concise but are harder to debug
str = "abc"
res = [s.capitalize() for s in str]
assert res == ['A', 'B', 'C']
