[FIXED] Anaconda Spyder shortcuts Ctrl+Enter and Shift+Enter are not working

Issue

Sorry for this noob question. I recently installed Anaconda Spyder UI for Python on MacOS. Within Spyder you see three windows, the python file (source code), the variable explorer and the IPython console.

I got two problems:

First, the shortcuts do not work. For instance: Run Cell = CTRL+ENTER and Run Cell and Advance is SHIFT+ENTER. But does not work.

Second, the output of the IPython console does not work. Let's assume the following code:

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

# Importing the dataset
dataset = pd.read_csv('Data.csv')
x = dataset.iloc[:, :-1].values
y = dataset.iloc[:, 3].values

x

Then the last line should print x as output onto the IPython console. But instead I get only this:

In [1]: runfile('/Users/guest/Development/data.py', wdir='/Users/guest/Development/')

And no Out [1]. Question: What am I doing wrong? I couldn't locate anything in the preferences dialog.

Solution

1. You need to use comments of the form #%% to break your files in cells, which are blocks of code you can evaluate independently. Then Cmd+Enter and Shift+Enter will work as expected, i.e. they will evaluate the current cell and stay on it or move to the next one, respectively.
2. About your second question, if you are running a file with the Run command (what you get when you press F5), you need to change your last line to print(x), because Run doesn't print by default.
