text = browser.find_element_by_css_selector('.dbaListing.listing.lastListing > td:nth-child(4) > span').text This is what I want my webdriver to wait for to be located/visible. How do I do that? Use WebDriverWait with the visibility_of_element_located Expected Condition : from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC wait = WebDriverWait(browser, 10) element = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".dbaListing.listing.lastListing > td:nth-child(4) >

I am trying to create a program that takes in a username and high score, if they are already a user they update to their new high score or just adds the high score if not. My code is: try: a = open("data", "r+") except FileNotFoundError: a = open("data", "w") a = open("data", "r+") b = a.read() user = input("Username: ") user2 = list(user) if user in b: old = input("What is your old highscore? ") new = input("What is your new highscore? ") b2 = b.split() for line in b2: #Where I want to edit. line=line.replace(old, new) print(line) else: new = input("What is your highscore? ") a.write(user + "

I'm new to Python and am working on a sensor. I'm building my code line by line and I have trouble with the encoding/decoding part for bytes to string. Same code, sometime it works, sometime it dosen't. Here is the code: import serial import time import os port = serial.Serial("/dev/ttyUSB0", baudrate=9600, timeout=1, bytesize=8) f_w = open('/home/myname/python_serial_output.txt','r+') port.send_break() while True: op = port.read(2) op_str = op.decode('utf-8') f_w.write(op_str) print(op_str) It didn't work the first time round, but worked on the second time. Why? Here is the error I get:

I am trying to print the min and max from a list of salaries that I am reading from a csv file, but first I must remove the $ from the value and don't know how.
