Do this: list(map(chr,[66,53,0,94])) In Python 3+, many processes that iterate over iterables return iterators themselves. In most cases, this ends up saving memory, and should make things go faster. If all you’re going to do is iterate over this list eventually, there’s no need to even convert it to a list, because you can still … Read more

Example: accented_string = u’Málaga’ # accented_string is of type ‘unicode’ import unidecode unaccented_string = unidecode.unidecode(accented_string) # unaccented_string contains ‘Malaga’and is of type ‘str’
Include the type specifier in your format expression: >>> a = 10.1234 >>> f'{a:.2f}’ ‘10.12’
You opened the file in binary mode: with open(fname, ‘rb’) as f: This means that all data read from the file is returned as bytes objects, not str. You cannot then use a string in a containment test: if ‘some-pattern’ in tmp: continue You’d have to use a bytes object to test against tmp instead: … Read more
It’s a function annotation. In more detail, Python 2.x has docstrings, which allow you to attach a metadata string to various types of object. This is amazingly handy, so Python 3 extends the feature by allowing you to attach metadata to functions describing their parameters and return values. There’s no preconceived use case, but the … Read more
