Question

Is it possible to convert the following to a python list comprehension:

values = [a,b,c,d,...]

converted_values = []
for item in values:
    if type(item) == datetime.date:
        converted_values.append(item)
    else:
        converted_values.append(item.decode('utf-8'))

Answer 1

You can use Conditional Expressions to make this work.

converted_values = [item if type(item) == datetime.data
                    else item.decode('utf-8')
                    for item in values]

Python conditionals are fairly readable. Here’s some examples to show how they work:

print("yes" if True else "no") # prints "yes"
print("yes" if False else "no") # prints "no"
