My code for Tic-Tac-Toe (beginner), compared to my mate that works at google's code.

Thought it would be interesting seeing someone beginner code, vs someone's professional code on the same project. After I sent him my code he replied with how he would have done it, as a comparison.

**My code:**

import random

def plyr1wintest(): #checks if player has 3 in a row
global winner
if (1 in plyr1list) and (2 in plyr1list) and (3 in plyr1list) or \

Updating Figure Display in Jupyter

Hello /r/IPython

&#x200B;

I'm not sure if this is the right place to ask this, but the jupyter subreddit doesn't seem very active. Anywho, I'm trying grabbing images from webcam and doing some processing on it, and I want the output from the code block to update, maybe redrawing the figure/axis so that the newer image shows. Here's what I have:

```
plt.ion()
webcam = init_cam() #sets resolution and stuff
fig, ax = plt.subplots(1)
axim = ax.imshow(tFrame) #Show some pre-grabbed image

while True:
frame = get(webcam) #gets image from webcam
axim.set_data(frame)
plt.show(block=False)
#plt.pause(1) #I've tried with and without pauses
```

And long story short, it doesn't update the figure and appears to only show the first frame. Am I doing something wrong? Is there another way to do this? Any help would be appreciated!

Basic Power Analysis Discrepancy

Hi all,

I'm working on a power analysis to better understand how the process works for linear regression and interactions effects. I'm trying to create a function that simulates a dataset, adds participants to it based on an argument that can be specified (e.g., to see how many more people one would need to have power reach a certain threshold), and then counts a proportion of p-values less than an alpha level. In this case, the model is
dv ~ dx_status + ybocs + dx_status*ybocs
and I'm interested in learning how many participants I'd need to get a statistically significant p-value for the interaction term.

Here is the code:

import pandas as pd
import numpy as np
import statsmodels.api as sm
import statsmodels.formula.api as smf

hyp2_pvalues_list = [] #create an empty list
np.random.seed(4) #sets a seed for the random number generator
def pwrcurve_hypoth2(addtogroup = 0, simulations = 1000, es = 0.5, dv_sd = 3.9, bdi_sd = 5, ybocs_sd = 5,
alpha = .05):
for x in range(simulations):
