sub(r"\s+", r"", version) >>> no_spaces 'py310' Remove extra whitespaceWhat if you just need to get rid of extra spaces (collapsing consecutive spaces)?We could use the string split and join methods, as before,
You get the following output: importre my_stringno_spaces# no_spaces is now "HelloWorld" To remove all spaces, usemy_string.replace(" ", "") strip()do in Python? To “trim” spaces—meaning to remove them only from the start and end of the string—use thestrip()method: my_string=...
Beware that in the likely case of using spaces in the description part, you need to quote it for your shell to get through to Nuitka and not be interpreted as Nuitka arguments. Console Window On Windows, the console is not opened by programs unless you say so. Nuitka defaults to not sho...
The bug: I specified UTF-8 encoding when writing the file but failed to do so when reading it, so Python assumed the system default encoding—Windows 1252—and the trailing bytes in the file were decoded as characters 'é' instead of 'é'. I ran Example 4-9 on a Windows 7 mach...

When you write tests, you often want to get rid of the print() function, for example, by mocking it away. Paradoxically, however, that same function can help you find bugs during a related process of debugging you’ll read about in the next section.Syntax in Python 2Show/Hide ...
