Applied Data Science with Python - Assignment 2.3: clicking on chart to select Y values
Hey all, I have the following code below:
import pandas as pd
import numpy as np
from scipy import stats
np.random.seed(12345)
scores = [np.random.normal(32000,20,3650).mean(),
np.random.normal(43000,10,3650).mean(),np.random.normal(43500,14,3650).mean(),
np.random.normal(48000,7,3650).mean()]
standarderrors1992 = stats.sem(np.random.normal(32000,20,3650))
standarderrors1993 = stats.sem(np.random.normal(43000,10,3650))
standarderrors1994 = stats.sem(np.random.normal(43500,14,3650))
standarderrors1995 = stats.sem(np.random.normal(48000,7,3650))
add1992 = 1.96*standarderrors1992
add1993 = 1.96*standarderrors1993
add1994 = 1.96*standarderrors1994
add1995 = 1.96*standarderrors1995
mean1992 = np.random.normal(32000,20,3650).mean()
mean1993 = np.random.normal(43000,10,3650).mean()
mean1994 = np.random.normal(43500,14,3650).mean()
mean1995 = np.random.normal(48000,7,3650).mean()
labels = [1992,1993,1994,1995]
add = [add1992,add1992,add1994,add1995]
1. This first part organises the raw data.
limits = []
def onclick(event):
plt.cla()
plt.bar(df["index"].values,df["values"].values,align='center',
alpha=0.5,yerr=add)
plt.xticks(labels)
limit = event.ydata
limits.append(limit)
if len(limits) >= 1:
plt.gcf().canvas.mpl_disconnect(plt.gcf().canvas.mpl_connect('button_press_event',
onclick))
plt.gcf().canvas.mpl_connect('button_press_event', onclick)
2. This next part allows the user to press on the graph to select a Y value.
This should be assigned to the variable 'limits'
dict = {mean1992:add1992,mean1993:add1993,mean1994:add1994,mean1995:add1995}
colourofbars = []
for key,value in dict.items():
if limits[0] > (key+(value)):
colour = 1
colourofbars.append(colour)
elif limits[0] < (key-(value)):
colour = 0
colourofbars.append(colour)
elif (limits[0] < (key+(value))) & (limits[0] > (key-(value))):
colour = ((key+(value))-limits[0])/((key+value)-(key-value))
colourofbars.append(colour)
df["colourofbars"] = colourofbars
3. Here, the list 'colourofbars' is appended based on the data above, and added
as a column to the dataframe 'df'.
cmap = plt.cm.rainbow
norm = matplotlib.colors.Normalize(vmin=1.5, vmax=4.5)
plt.bar(df.index,df.values,color=cmap(norm(df.colourofbars.values)),align='center',
alpha=0.5,yerr=add)
plt.xticks(labels)
sm = plt.cm.ScalarMappable(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? Am I on the right
lines?

Shared library missing from wheel (custom build)
Hi,
I'm playing around with generating extension moudle to Python in Go. This is
for a blog post - not production ready.
The Go code is compiled to a shared library and the Python module is using
ctypes to call the Go code in the shared library. I know it's know a classic
extension module with PyModule_Create and friends, but that's for later...
maybe.
The setup.py is defined as
---
from subprocess import call
from setuptools import Extension, setup
from setuptools.command.build_ext import build_ext
class build_go_ext(build_ext):
def build_extension(self, ext):
ext_path = self.get_ext_filename(ext.name)
cmd = ['go', 'build', '-buildmode=c-shared', '-o', ext_path]
cmd += ext.sources
out = call(cmd)
if out != 0:
raise RuntimeError('Go build failed')
setup(
name='checksig',
version='0.1.0',
py_modules=['checksig'],
ext_modules=[
Extension('_checksig', ['checksig.go', 'export.go'])
],
cmdclass={'build_ext': build_go_ext},
)
---
When I run "python setup.py bdist_wheel", I see that that
_checksig.cpython-38-x86_64-linux-gnu.so is being built. But when I look at the
content of dist/checksig-0.1.0-cp38-cp38-linux_x86_64.whl it's not there.
What am I missing?
You can view the whole (WIP) project at
https://github.com/ardanlabs/python-go/tree/master/pyext
Thanks,
Miki

There are a number of books that can help with this, such as "Invent Your Own Computer Games with Python" by Al Sweigart (through No Starch Press, or free on his website). In the end, programming isn't "for everyone". Anyone may theoretically learn how to do it, even do it well, but that doesn't mean they'll necessarily enjoy it. I'm actually rather curious why you *need* to become "efficient" (proficient?) in Python? Work requirement? By the way, you should put your message the the BODY of the email, not in the subject line.

The usual workaround is to append an underscore: 'from_'.
True, but ick. ;-) It's like a dangling preposition.
It is, in a sense, standard practice. It is used, for instance, for
tcl/tk names that are python keywords. The option / argument name 'in'
is written 'in_' when written without quotes in a call.
f(in_='.') and f(**{'in':'.'}) have the same effect.

When creating a nested dictionary of dataframes, how can I name a dictionary based on a list name of the dataframe?
When creating a nested dictionary of dataframes, how can I name a
dictionary based on a list name of the dataframe?
Given the following:
# START CODE
import pandas as pd
cars = {'Brand': ['Honda Civic','Toyota Corolla'],
'Price': [22000,25000]
}
df_cars = pd.DataFrame(cars, columns = ['Brand','Price'])
trucks = {'Brand': ['GMC Sierra','Ford F-150'],
'Price': [5,48000]

df_trucks = pd.DataFrame(trucks, columns = ['Brand','Price'])

dict_of_dfs = {}
for df in list_of_dfs:
dict_of_dfs[name_of_df] = {} # Not sure here
dict_of_dfs[name_of_df]['results'] = df # Not sure here
# END CODE
I am trying to use a for loop that performs the following:
# START CODE
dict_of_dfs['df_cars'] = {}
dict_of_dfs['df_cars']['results'] = df_cars
dict_of_dfs['df_trucks'] = {}
dict_of_dfs['df_trucks']['results'] = df_trucks
# END CODE
The above code should produce the following desired output:

'df_cars': {
'results':

0 Honda Civic 22000
1 Toyota Corolla 25000},
'df_trucks': {
'results':
Brand Price
0 GMC Sierra 5
1 Ford F-150 48000}
}
I've read multiple threads, used the module varname, and tried using
enumerate() but have been unsuccessful.

Try checking what kind of element it finds for you (perhaps by logging
searchBox.tag_name). There might be multiple elements matching the
search criteria.
