Python Bridge Examples

Python Examples

Provide these examples in the Z Code Window. Connect to Language Kernal with Jupyter (for example: http://localhost:8888 (as well as a token for the session) into the Z Config Panel. In ZAP, CTRL+SHIFT+CLICK on any language (server) automatically connects to an instance of Kernal, and no token is required.

Example 1:

def prime(x, y):
    prime_list = []
    for i in range(x, y):
        if i == 0 or i == 1:
            continue
        else:
            for j in range(2, int(i/2)+1):
                if i % j == 0:
                    break
            else:
                prime_list.append(i)
    return prime_list


# Driver program
starting_range = 2
ending_range = 7
lst = prime(starting_range, ending_range)
if len(lst) == 0:
    print("There are no prime numbers in this range")
else:
    print("The prime numbers in this range are: ", lst)

prime(2,40)

print(prime(2,40))

print(prime(2,400))

Example 2:

Demonstrates how to include a python library.

import math
print(34+435)
math.sin(34)

Exmaple 3:

// draw graph with python
// trying to draw a graph

# importing the required module
import matplotlib.pyplot as plt

# x axis values
x = [1,2,3]
# corresponding y axis values
y = [2,4,1]

# plotting the points 
plt.plot(x, y)

# naming the x axis
plt.xlabel('x - axis')
# naming the y axis
plt.ylabel('y - axis')

# giving a title to my graph
plt.title('My first graph!')

# function to show the plot
plt.show()

Example 4:

From [[1]]

Install python libraries using pip on the server machine (or local desktop as relevant).

Such as:

pip install pillow

pip install numpy

pip install matplotlib

import matplotlib.pyplot as plt

def draw_fractal(ax, levels=4, x=0, y=0, size=1):
    if levels == 0:
        ax.add_patch(plt.Rectangle((x, y), size, size, color='navy'))
    else:
        size3 = size / 3
        for i in range(3):
            for j in range(3):
                if (i + j) % 2 == 0:
                    draw_fractal(ax, levels - 1, x + i * size3, y + j * size3, size3)

fig, ax = plt.subplots()
ax.set_aspect(1)
ax.axis('off')
draw_fractal(ax)
plt.show()

More Python Examples

Below examples show basic examples to more advanced ones with data transfer etc.

Example 1:

# This program adds two numbers

num1 = 1.5
num2 = 6.3

# Add two numbers
sum = num1 + num2

# Display the sum
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

--

print(num1-num2)

Example 2: Postpile Execution

This examples shows postpile computation of print("{= s1="+SIN(sum)+"=}"), which prints out the string

{= s1=SIN(sum) =}

and this results in the code between {= and =} to execute in Z to achieve postpile execution.

# This program adds two numbers

num1 = 1.5
num2 = 6.3

# Add two numbers
sum = num1 + num2
print("{= s1="+SIN(sum)+"=}")


// Shows post processing of python into Z.
# This program adds two numbers

num1 = 1.5
num2 = 6.3

# Add two numbers
sum = num1 + num2
print("{= s1=SIN(" + str(sum) + ")=}")
