Image Custom Handling exceptions using Try and Except. If you are not aware of what error might come up, you can use the following code. Here we have used the keyword Exception and passed it to a variable called e. In case any problem occurs, we ask our code to print e, instead of showing the complete stack trace of the problem. Image Generic Exception Handling. Here is how the output for the same looks:. Image Capturing response codes from URLs. Okay, so for writing a report we need to open another file, in write mode.
Not in append mode, because if we append, this will write in the file every time we run the program. Also the position of the write statement matters a lot, because if we include it in the for loop, it will overwrite the file every time and we will be left with output from the last iteration only.
Here is the code snippet which will fulfill the purpose:. We have chosen CSV as it is relatively easier to work on. Any other file format can also be picked up as per your convenience. Once we have received the response code, we checked if there is any exception which might have happened at network layer.
In case any issue occurred, we set the false value to a success variable. Got back from the try except block, and checked if success is true or false. In case of success being false, we simply wrote a negative sign [-], Sr. In case of success variable being true, we checked further is the response code was or not. In case this was , we wrote negative sign, sr.
URL, status code returned from server. Also as the user might be impatient, and might get panic while all this is happening at the backend, so we printed all these values on screen as well. So this is it. By now we are ready with a small piece of code which will take a file name from the user which will be holding a list of URLs on which test is to be performed.
These URLs will be parsed, processed and will be checked if they can be accessed directly without login or not. Note: Obviously, status-codes might be different for different websites, so you can tweak the logic. I hope this was an easy tutorial with real time snapshots and code snippets which would help you a lot while learning. This was quite a basic one. I also missed lot of details as I thought they are not relevant to this specific tool. I will include required details in every blog post.

Most developers have wised up to SQL injection hacks, so this probably won't work on the majority of websites. Still, if you find an older website with a login page, you may be able to use this hack to gain access without knowing a password. Check the website for SQL vulnerabilities. The simplest way to do this is to enter ' this is the single quote mark into the username field, and then click the Log In or Sign In button.
If you get a simple error that says the username or password is incorrect, this method won't work. Enter the injection code into the "Password" field.
If the single quote you entered into the Username field before is still there, delete it—you'll want that field to be blank.
Click the Login button. If you were able to log in successfully, great! If you're still not able to log in, the site is protected against this type of hack. Method 2. Go to the login page of the website you want to hack. You can use any modern web browser, including Chrome, Firefox, or Safari. You're going to need a text editor and you'll have to copy and paste the code below, then save it as a '. Here is the code for the batch file version Scroll to the bottom to know what some advanced looking parts do.
The non-bold text is the code :. At the very bottom where it says "echo msgbox All of the "ping You can change their times, but I suggest looking up how it works before changing that.
For this part, there isn't really anything to code, so I just converted it with a converter and you can download it here. This is how you change font in VSCode after installing it. The well renowned font Operator Mono does not come with native support for ligatures. However, if you are a big fan of ligatures, you can add them using this library.
Indent with style. This extension colorizes the indentation in front of your text alternating four different colors on each step. The default indentation setting colors the indentation following a rainbow scheme. I however customized my own to follow different shades of grey. If you wish yours to look like this example, copy and paste the following snippet in your settings. This is a great visual tweak. Basically he switched the title bar colors on different projects to recognize them easily and help the audience distinguish between them too.
This is really useful if you work on apps that may have the same code or file names, for example, a react-native mobile app and a react web app. This is done by editing Title Bar settings in the Workspace Settings for each project in which you want different title bar colors.
If you do not know Emmet , then you are probably someone that likes typing it all. Emmet enables you to type an abbreviated code and get the returned corresponding tags. Imagine you want to wrap all of these but as individual lines.
In case you want to jump right into Emmeting, this is the Emmet Cheatsheet. You can select a whole tag in VS Code by using the balance inward and balance outward Emmet commands. No one likes typing very long statements like console. It can be really irritating, mostly when you just want to output something really fast, view its value, then continue coding.
What if I told you you could console log anything as fast as Lucky Luke?
