问题 Let's say I have a list that contains 10,000+ proxies proxy_list = ['ip:port','ip:port',.....10,000+ items] How do I iterate it to get the proxies that works for my pc? Using the following code it is possible to find it , but takes 5*10,000 seconds to get completed. How would I iterate through the list faster? import requests result=[] for I in proxy_list: try: requests.get('http:\\www.httpbin.org\ip',proxies = {'https' : I, 'http' : I } ,timeout = 5) result.append(I) except: pass 回答1: You

问题 Here's how I plot the heat map: sns.heatmap(table, annot=True, fmt='g', annot_kws={'size':24}) The thing is, size set only the font size of the numbers inside the heatmap. Which parameter I should use in annot_kws to set the font size of the labels on the axes? Thanks 回答1: You cannot change those directly in the call to heatmap , but you can instruct matplotlib to change the font size either in plt.rcParams directly, or using a context manager: uniform_data = np.random.rand(10, 12) plt.figure

问题 I'm doing this code excercise for trying out functional programming in python, and I ran into problems with sum(), list(), and map objects. I don't understand what I'm doing wrong, but the list() function seems to be screwing with my map object. This is the code I have: people = [{'name': 'Mary', 'height': 160}, {'name': 'Isla', 'height': 80}, {'name': 'Sam'}] heights = map(lambda x: x['height'], filter(lambda x: 'height' in x, people)) print(len(list(heights))) print(sum(list(heights)))

问题 I've been making a basic calculator with Python and I have come across this issue. After the calculations are made "Invalid Number" always prints and then the pause happens. I think it has something to do with the newline breaking the if block but I'm not sure. Any help will be appreciated. Thanks in advance. def badnum(): print("Invalid Number") print("Press enter to continue") input("") def main(): print("Select an action ") print("1.) Add") print("2.) Subtract") print("3.) Multiply") print
