readfile

I am trying to get my python script to read a text file with a list of file names with extensions and print out when it finds a particular extension (.txt files to be exact). It reads the file and goes through each line (I've tested by putting a simple "print line" after the for statement), but doesn't do anything when it sees ".txt" in the line. To avoid the obvious question, yes I'm positive there are .txt files in the list. Can someone point me in the right direction? with open ("file_list.txt", "r") as L: for line in L: if line.endswith(".txt"): print ("This has a .txt: " + line) Each line

I'm serving downloads from a URL to my users through a PHP script. When using readfile() I get the maximum download speed my connection can support (about 2.5MB/s) however when I use the fopen, fread, fclose route the download speed is very, very slow (about 1-2KB/s). Here's my code: header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename=' . $filename); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate'); header('Pragma: public'); header('Content

json文件 首先要创建一个json文件，这里推荐一个google插件（WEB前端助手（Fehelper）），可以直接从一个接口中copy一个response，放进插件的输入框中，它会自动格式化代码，并且右上角有一个下载为json格式。但是这个下载的json文件有个问题，需要把第一行的注释去掉。 因为我使用的koa2框架，所以写法我就按照koa2的规则写 node读文件 1234567891011121314 const fs=require('fs');const readFile = function(){ return new Promise(function(resolve,reject){ fs.readFile( './public/config/staff.json',function (err,data) { if(err) return reject(error) resolve(JSON.parse(data)); }); })}let staffJson = await readFile(); node写文件 123456 //query.staff 是你要改写的内容fs.writeFile('./public/config/staff.json',query.staff,function (err) { if(err){ console.log(err);

My .txt file looks like this: ![enter image description here][1] How can I read my txt file into a string object that can be printed in the same format as above? I have tried: with open ("/Users/it/Desktop/Classbook/masterClassList.txt", "r") as myfile: data = myfile.read() for item in data: print item This code prints every character on a new line. I need the txt file to be a string in order to call string methods, particularly 'string.startswith()' As you can see, in my IDE console, the lines are printing with a black line of spaces in between each line of content. How can I eliminate these

I am currently trying to read a txt file from a website. My script so far is: webFile = urllib.urlopen(currURL) This way, I can work with the file. However, when I try to store the file (in webFile ), I only get a link to the socket. Another solution I tried was to use read() webFile = urllib.urlopen(currURL).read() However this seems to remove the formating ( \n , \t etc) are removed. If I open the file like this: webFile = urllib.urlopen(currURL) I can read it line by line: for line in webFile: print line This will should result in: "this" "is" "a" "textfile" But I get: 't' 'h' 'i' ... I

问题所在关键点： base64方法执行没有拿到url，而是代码报错，导致url是个Error。 来源： https://www.cnblogs.com/kpengfang/p/11677401.html

I'm using ReadFile() on Windows to read data from a serial port. This code was working fine at one point in time, but it's now failing and I'm trying to track down the source of the problem, so I doubt it's a problem with the serial configuration or timeouts, since none of that has changed. ReadFile() returns false, indicating that an error occurred. However, when I immediately check the value of GetLastError() , it returns 0, which is ERROR_SUCCESS . The number of bytes read is 0, so I'm inclined to think that indeed something has gone wrong, but that error code is utterly useless. Any ideas?
