I'm in Python 3.3 and I'm only entering these 3 lines:
import sklearn as sk
import numpy as np
import matplotlib.pyplot as plt
I'm getting this error:
SyntaxError: multiple statements found while compiling a single statement
What could I be doing wrong?

I had the same problem. This worked for me on mac (and linux):
echo "set enable-bracketed-paste off" >> ~/.inputrc
In the shell, you can't execute more than one statement at a time:
>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement
You need to execute them one by one:
>>> x = 5
>>> y = 6
>>>
When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.
x=6 \n x=6 and it will work just fine. Its impossible to say without a full traceback, and I think the actual answer is more towards jmu's
SyntaxError: unexpected character after line continuation character..
x = 5; y = 6 . You need to go into script mode.A (partial) practical work-around is to put things into a throw-away function.
Pasting
x = 1
x += 1
print(x)
results in
>>> x = 1
x += 1
print(x)
File "<stdin>", line 1
x += 1
print(x)
^
SyntaxError: multiple statements found while compiling a single statement
>>>
However, pasting
def abc():
x = 1
x += 1
print(x)
works:
>>> def abc():
x = 1
x += 1
print(x)
>>> abc()
2
>>>
Of course, this is OK for a quick one-off, won't work for everything you might want to do, etc. But then, going to ipython / jupyter qtconsole is probably the next simplest option.
You are using the interactive shell which allows on line at a time. What you can do is put a semi-colon between every line, like this -
import sklearn as sk;import numpy as np;import matplotlib.pyplot as plt.
Or you can create a new file by control+n where you will get the normal idle. Don't forget to save that file before running. To save - control+s. And then run it from the above menu bar - run > run module.
Long-term solution is to just use another GUI for running Python e.g. IDLE or M-x run-python in Emacs.
The solution I found was to download Idlex and use its IDLE version, which allows multiple lines.
This was originally added to Revision 4 of the question.
I am on windows executing python code through wsl.
What worked for me is switching to Jupyter Notebook. It's easy to get with pip install jupyter; then deploy with jupyter notebook.
It allows pasting multiple lines into each 'cell' as well as plenty more functionality:
