问题 I am trying to scrape the CDC website for the data of the last 7 days reported cases for COVID-19. https://covid.cdc.gov/covid-data-tracker/#cases_casesinlast7days I've tried to find the table, by name, id, class, and it always returns as none type. When I print the data scraped, I cant manually locate the table in the html either. Not sure what I'm doing wrong here. Once the data is imported, I need to populate a pandas dataframe to later use for graphing purposes, and export the data table

问题 I am trying to plot my data in the csv file. Currently my dates are not shown properly in the plot also if i am converting it. How can I change it to show the proper dat format as defined Y-m-d? The second question is that I am currently plotting all the dat in one plot but want to have for every Valuegroup one subplot. My code looks like the following: import pandas as pd import matplotlib.pyplot as plt csv_loader = pd.read_csv('C:/Test.csv', encoding='cp1252', sep=';', index_col=0).dropna()

问题 In my python script I'm having a list that has the following structure: ['00:00', 'abc', '2', 'xyz'] ['00:01', 'cde', '3', 'sda'] and so on. I want to write this list to csv file in a way that every element is in separate row and every string in one element is in separate column. So I want to end up with the following result in csv file: A | B | C | D 1 00:00 | abc | 2 | xyz 2 00:01 | xyz | 3 | sda Currently I have a code like this: with open('test1.csv',mode='w',encoding='UTF-8') as result

问题 I need to upload some 2000 documents to specific users in salesforce. I have a csv file that has the Salesforce-assigned ContactID, as well as a direct path to the files on my desktop. Each contact's specific file url has been included in the csv. How can I upload them all at one and, especially, to the correct contact? 回答1: You indicated in the comments / chat that you want it as "Files". The "Files" object is bit more complex than Attachments, you'll need to do it in 2-3 steps. What you see

问题 I have more than 10000 csv files in a folder and I'm trying to merge them by line using awk but if I run this command: printf '%s\n' *.csv | xargs cat | awk 'FNR==1 && NR!=1{next;}{print}' *.csv > master.csv I get the following errors: /usr/bin/awk: Argument list too long and printf: write error: Broken pipe 回答1: With the printf and xargs parts, you are sending the contents of the csv files into awk, but you also provide the filenames to awk. Pick one or the other: I'd suggest: { printf '%s\n
