urllib.urlretrieve with custom header

I found a way where you only have to add a few extra lines of code… import urllib.request opener = urllib.request.build_opener() opener.addheaders = [(‘User-agent’, ‘Mozilla/5.0’)] urllib.request.install_opener(opener) urllib.request.urlretrieve(“type URL here”, “path/file_name”) Should you wish to learn about the details you can refer to the python documentation: https://docs.python.org/3/library/urllib.request.html

Dependency Inversion in Python

The principle Robert C. Martin’s definition of the Dependency Inversion Principle consists of two parts: High-level modules should not depend on low-level modules. Both should depend on abstractions. Abstractions should not depend on details. Details should depend on abstractions. Just to clarify… a module could be a function, a class, a file… a piece of … Read more

How can I plot a confidence interval in Python?

There are several ways to accomplish what you asking for: Using only matplotlib from matplotlib import pyplot as plt import numpy as np #some example data x = np.linspace(0.1, 9.9, 20) y = 3.0 * x #some confidence interval ci = 1.96 * np.std(y)/np.sqrt(len(x)) fig, ax = plt.subplots() ax.plot(x,y) ax.fill_between(x, (y-ci), (y+ci), color=”b”, alpha=.1) fill_between … Read more

Accepting output of the socket generated by Python in MQL5

Please find a running example. Important element is to create byte object of the payload instead of string before you send as reply. socket object produces and ingests only bytes import socket import threading import sys def actual_work(data): print(data) return b’ACK’ def daemon(): sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) sock.bind((‘127.0.0.1’, 6666)) print(“Listening on udp … Read more

ValueError: The number of FixedLocator locations (5), usually from a call to set_ticks, does not match the number of ticklabels (12)

I also stumbled across the error and found that making both your xtick_labels and xticks a list of equal length works. So in your case something like : def month(num): # returns month name based on month number num_elements = len(x) X_Tick_List = [] X_Tick_Label_List=[] for item in range (0,num_elements): X_Tick_List.append(x[item]) X_Tick_Label_List.append(month(item+1)) plt.xticks(ticks=X_Tick_List,labels=X_Tick_LabeL_List, rotation=25,fontsize=8)
