问题 I'm trying to write data to a csv file. The data is in a confusing format and I cannot change it. This is how the data dictionary looks like. How do i write this data in a csv file? [{'box': [277, 90, 48, 63], 'confidence': 0.99, 'keypoints': { 'left_eye': (291, 117), 'right_eye': (314, 114), 'nose': (303, 131), 'mouth_left': (296, 143), 'mouth_right': (313, 141)} }] I tried using the code below however, using this code only writes the field names in the csv file and not the values. import

问题 I'm new to coding and by default new to Python, so please excuse my ignorance...I'm working on it. I am trying to write some code (Python 2.7) to take specific headers from multiple CSV files and export them as a single file. Here is my code: import csv, os path = 'C:/Test/' for fn in os.listdir(path): if ".csv" in fn: with open(fn, 'rb') as f: with open('C:/Test/fun/output.csv', 'wb') as fou: reader = csv.DictReader(f, delimiter=",", quotechar="|") writer = csv.DictWriter(fou, delimiter=",",

问题 It is very simple to read a standard CSV file, for example: val t = spark.read.format("csv") .option("inferSchema", "true") .option("header", "true") .load("file:///home/xyz/user/t.csv") It reads a real CSV file, something as fieldName1,fieldName2,fieldName3 aaa,bbb,ccc zzz,yyy,xxx and t.show produced the expected result. I need the inverse, to write standard CSV file (not a directory of non-standard files). It is very frustrating not to see the inverse result when write is used. Maybe some

问题 [DISCLAIMER] I have been through plenty of the other answers on the area, but they do not seem to work for me. I want to be able to export the data I have scraped as a CSV file. My question is how do I write the piece of code which outputs the data to a CSV? Current Code import requests from bs4 import BeautifulSoup url = "http://implementconsultinggroup.com/career/#/6257" r = requests.get(url) req = requests.get(url).text soup = BeautifulSoup(r.content) links = soup.find_all("a") for link in

问题 I have an Excel workbook with powerpivot data in Excel data model. I don't have the file used to import the data into powerpivot.

I found this VBA which appears to work for smaller files but for larger ones I get a timeout error. Option Explicit Public Sub ExportToCsv() Dim

问题 I would like to export a Mongo Collection to an .csv. Mongo provides a solution for this but it is limited to the shell. http://docs.mongodb.org/manual/reference/mongoexport/ I'm using the native driver for node.js and would like to be able to do this in a script as opposed to being invoked from the shell. 回答1: If you're just looking to run the mongoexport command from your node.js app, you can use child_process.spawn to do that. 回答2: You can script the shell. Check this out. Might help. http
