[FIXED] How to draw lines on a plot of points in python

Issue

How can one join the points with lines in the following code?

import matplotlib.pyplot as plt
for i in range(1, 10):
    y = i**2
    plt.plot(i, y, '-o')
    plt.show

Using plt.scatter or plt.scatter/plt.plot/plt.show don't work either.

Solution

The code would not plot properly since plt.plot and plt.show() is looping. You might want to store your update i & y values in a list before you plot it.

import matplotlib.pyplot as plt
x = []
y = []
for i in range(1, 10):
    x.append(i)
    y.append(i**2)

plt.plot(x,y) 
plt.show()
