Think this is a bug of VS Code. When you use “run selection/line in python terminal” command, VS Code starts python interpreter and doesn`t quit it after completion. You should use exit() command in python interpreter window to end python session. After that “run python file in terminal” will work fine.
The SyntaxError: unexpected EOF while parsing means that the end of your source code was reached before all code blocks were completed. A code block starts with a statement like for i in range(100): and requires at least one line afterwards that contains code that should be in it. It seems like you were executing … Read more
You can’t initialize member variables to anything that is not static, and you’re trying to call a function. From the manual: This declaration may include an initialization, but this initialization must be a constant value–that is, it must be able to be evaluated at compile time and must not depend on run-time information in order … Read more
Using parentheses to unpack the arguments in a lambda is not allowed in Python3. See PEP 3113 for the reason why. lambda (k, v): (-v, k) Instead use: lambda kv: (-kv[1], kv[0])
Instead of downgrading, you can also change the default terminal from cmd to powershell. To do so, go to your settings.json and replace the “terminal.integrated.shell.windows” parameter from the path to cmd (e.g. “C:\\Windows\\System32\\cmd.exe”) to the path to powershell (e.g. “C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe”) If you are using VScode press ctrl+shift+p and search for default terminal and change it … Read more
As described here Class member variables are called “properties”. You may also see them referred to using other terms such as “attributes” or “fields”, but for the purposes of this reference we will use “properties”. They are defined by using one of the keywords public, protected, or private, followed by a normal variable declaration. This … Read more
As suggested by Josh Lee in the comment section, that kind of string interpolation was added in Python 3.6 only, see What’s New In Python 3.6 (here it’s called “PEP 498: Formatted string literals”). You, however, seems to be using Python 3.5.2, which does not support that syntax.
For Babel <6 The easiest way to solve this problem is: npm install babel-preset-es2015 –save-dev Add .babelrc to the root of the project with contents: { “presets”: [ “es2015″ ] } Ensure that you are running mocha with the “–compilers js:babel-core/register” parameter. For Babel6/7+ npm install @babel/preset-env –save-dev Add .babelrc to the root of the … Read more
When an error is reported on a line that appears correct, try removing (or commenting out) the line where the error appears to be. If the error moves to the next line, there are two possibilities: Either both lines have a problem (and the second may have been hidden by the first); or The previous … Read more
2. is parsed as a float, so 2.__add__ is a SyntaxError. You can evaluate (2).__add__(3) instead. In [254]: (2).__add__(3) Out[254]: 5
