在python中初始化一个空的csv？

Question

是否可以在python中初始化一个空的csv文件？我想初始化一个，然后将目录中的每个csv文件逐个合并到其中。

Answer 1

read()

，write()

可以通过open('file' 'a')向append和files = ['the', 'files', 'here'] output = '/output/file/here' for file in files: with open(file, 'r') as input_file: with open(output, 'a') as output_file: output_file.write(input_file.read()) 发送文件

spa.factory("linkFactory", function() {
        var linkFactoryObject = {};
        linkFactoryObject.currentLink = "home";
        linkFactoryObject.setRoute = function(route) 
        {
          linkFactoryObject.currentLink = route;
        };
        return linkFactoryObject;
    });

    spa.run(['linkFactory','$rootScope',function(linkFactory,$rootScope) {
      $rootScope.$on('$routeChangeStart', function(event, next, current) {
        linkFactory.setRoute(next.$$route.originalPath);
      });
    });

无需先创建空文件。
