When things go wrong, Python tries to be helpful by providing a
"traceback". Please copy-paste
larMappable(cmap=cmap, norm=norm)
plt.gcf().colorbar(sm)
plt.show()
4. Here, a different colour is assigned to each bar in the bar chart depending
on the values in the column 'colourofbars'. I then try to plot a legend showing
this colour gradient scale.
However, I keep getting the error: IndexError: list index out of range. Could
anyone give me a helping hand as to where I am going wrong?

Because of what an index means for the 'list' type, that's equivalent to
saying "the result of `len(fld)` may be 3, 4, or 5".
> What's the neatest
I have a list created by:-
fld = shlex.split(ln)
It may contain 3, 4 or 5 entries according to data read into ln.
What's the neatest way of setting the fourth and fifth entries to an
empty string if they don't (yet) exist? Using 'if len(fld) < 4:' feels
clumsy somehow.

Here are a few ways.

then it gives an
error of "list index out of range."
The strange thing is that it will sometimes run for 10 iterations sometimes
for only a few and sometimes won't run at all (seemingly arbitrary).
Here is some of the code:
for _ in range(100):
handA=deal_hand(DECK) #deals 2 &#x
I am a relatively new python user. I am writing an economic simulation of a
card-game. The simulation runs fine for a few iteration but then it gives an
error of "list index out of range."
The strange thing is that it will sometimes run for 10 iterations sometimes for

And the former raises an exception if the value is not found, while
the latter returns None if the value is not found.
