Trouble passing arguments through an initialiser function in javascript

With these it helps This problem is not hard to understand. In a function, arguments is an array-like object which contains all the arguments passed in. In your second example, you passed an array as argument to init function, so arguments in init function is a 2D array.
code :
Ex2 = function() {   
    init = function() {
        myVar = [];
        myVar = Array.apply( myVar, arguments );//arguments: [["red", "green", "blue"]]
        return myVar;
    };

    return init( arguments );//arguments: ["red", "green", "blue"]  
};
Ex2 = function() {
    var init = function(argu) {
        return Array.apply( 0, argu );//argu: ["red", "green", "blue"]
    };
    return init( arguments );
};
ex2 = new Ex2( 'red', 'green', 'blue' );
console.log( ex2 );//["red", "green", "blue"]

will help you I want to run a python script 5 times. The output from each run is an image, and I want 5 images saved at the end. To do this I am using the os.system() command, and I end up with the following error: , You should call it with just one string as follows:
code :
os.system('python main.py input laska.png output laska_save{}.png'.format(i))

will help you You are really close to the right solution! The route above the definition should also contain the arguments needed for the function: @app.route('/piechart.png///'), and you should also specify these arguments when calling the url:
code :
from flask import Flask, render_template_string, url_for, make_response
from io import BytesIO
import matplotlib
matplotlib.use('Agg')
from matplotlib import pyplot as plt

app = Flask(__name__)

@app.route('/piechart.png/<x>/<y>/<z>', methods=['GET', 'POST'])
def chart_maker(x, y, z):
    labels = 'Positive', 'Negative', 'Neutral'
    sizes = [x, y, z]
    colors = ['gold', 'pink', 'lightskyblue']
    explode = (0, 0, 0)
    plt.axis('equal')
    plt.pie(sizes, explode=explode, labels=labels, colors=colors,
            autopct='%1.1f%%', shadow=True, startangle=140)
    img = BytesIO()
    plt.savefig(img)
    response = make_response(img.getvalue())
    response.mimetype = 'image/png'
    return response

@app.route('/display_chart')
def display_chart():
    return render_template_string('<img src="{{url_for("chart_maker", x=1, y=2, z=3)}}">')

app.run()

this one helps. You don't have to use a decorator with decorator syntax. You can wait to "decorate" fib until after you have the desired cache size. For example,
code :
import argparse
from functools import lru_cache

def main():
    global fib
    # boilerplate for parsing command line arguments
    parser = argparse.ArgumentParser()
    parser.add_argument("--cache_size", default="10")
    parser.add_argument("--fibo_num", default="20")
    args = parser.parse_args()
    cache_size = int(args.cache_size)
    fibo_num = int(args.fibo_num)

    fib = lru_cache(maxsize=cache_size)(fib)

    caller_func(fibo_num)

#Intermediate function that is supposed to call decorated function
def caller_func(fib_num): 
    print(fib(fib_num))

def fib(n): 
    if n < 2:
        return n
    return fib(n-1) + fib(n-2)

if __name__ == "__main__":
    main()

I think the issue was by ths following , Your solution isn't far off, but you are making your life difficult by using the onchange HTML attribute. Neither the arguments local variable nor the nums argument have any relevance in your case.
I would instead use the addEventListener method. This is both easier to read, and makes it trivial to get ahold of the input's value when it is changed. Something like this (Plunker):
