def counter_label(label):

def count():

global counter

label.config(text=str(counter))

label.after(1000, count)

count()

root = tk.Tk()

root.title("Counting Seconds")

label.pack()

counter_label(label)

button = tk.Button(root, text='Stop', width=25, command=root.destroy)

button.pack()

root.mainloop()

Generate random numbers with normal distribution

 1.Generate normal distribution data of Size 2 × 3

   from numpy import random
   x = random.normal(size=(2, 3))

2. Generate normal distribution with mean 250 and standard deviation 10

    from numpy import random
    x = random.normal(loc=250, scale=10, size=(2, 3))

Python Random Module

 import random

random.random() 

random.uniform(1, 10)

random.randint(1, 10)

random.randrange(0, 101, 2)

random.choice('abcdefghij') 

items = [1, 2, 3, 4, 5, 6, 7]

random.shuffle(items)

items

random.sample([1, 2, 3, 4, 5],  3)

Python may get pattern matching syntax

PEP 622 -- Structural Pattern Matching is PEP proposes adding pattern matching statements  to Python in order to create more expressive ways of handling structured heterogeneous data. The authors take a holistic approach, providing both static and runtime specifications.
