Examples of how to generate a random number between 0 and 1 in python

### Using function random.uniform()

To generate a random number between 0 and 1, there are several solutions for example using the random module with uniform():

`>>> import random`

`>>> x = random.uniform(0,1)`

`>>> x`

`0.24773029475050623`

Generate a list of random numbers between 0 and 1:

`>>> list_rx = [random.uniform(0,1) for i in range(10000)]`

and plot:

`>>> import matplotlib.pyplot as plt`

`>>> plt.hist(list_rx,density=1)`

`(array([0.96310412, 0.95410315, 1.04511299, 1.05211375, 1.01811007,`

`1.04211267, 0.98210618, 1.00010812, 0.97710564, 0.96710456]), array([7.53999199e-05, 1.00064589e-01, 2.00053777e-01, 3.00042966e-01,`

`4.00032155e-01, 5.00021344e-01, 6.00010532e-01, 6.99999721e-01,`

`7.99988910e-01, 8.99978098e-01, 9.99967287e-01]), <a list of 10 Patch objects>)`

`>>> plt.show()`

### Using numpy random.uniform

Another solution is to generate a matrix with random numbers between 0 and 1 using numpy:

`>>> import numpy as np`

`>>> R = np.random.uniform(0,1,10)`

`>>> R.shape`

`(10,)`

`>>> R`

`array([0.78628896, 0.16248914, 0.01916588, 0.37004623, 0.94038203,`

`0.68926777, 0.13643452, 0.62616651, 0.69852288, 0.27889004])`
