_bag_of_words() which returns a list of tuples in the (word, word_count) format, sorted by the word count.
Finally, we print the top ten most common words.
Typically, for this, you’d create a Bag of Words Model, using libraries like NLTK, though, this implementation will suffice. Let’s run the script and provide our to it:
$ python
Most frequent 10 words [(‘the’, 15633), (‘and’, 6959), (‘of’, 5237), (‘to’, 4449), (‘his’, 3440), (‘in’, 3158), (‘with’, 2445), (‘a’, 2297), (‘he’, 1635), (‘from’, 1418)]

Conclusion
In this article, we’ve explored multiple ways to read a file line-by-line in Python, as well as created a rudimentary Bag of Words model to calculate the frequency of words in a given file.
Parsing text with Python – vipinajayakumar
I hate parsing files, but it is something that I have had to do at the start of nearly every project. Parsing is not easy, and it can be a stumbling block for beginners. However, once you become comfortable with parsing files, you never have to worry about that part of the problem. That is why I recommend that beginners get comfortable with parsing files early on in their programming education. This article is aimed at Python beginners who are interested in learning to parse text files..

What does it mean to parse a file in Python?
So “parsing” or “parsed” means to make something understandable. For programming this is converting information into a format that’s easier to work with. So the phrase “parsed as a string” means we are taking the data from the csv file and turning it into strings.Jan 23, 2020Hello how are you? to all. It turns out that when trying to use vJoy with irFFB for iRacing, I find that the steering wheel turn blocker in rFactor 2 does not work well. With my TS-PC, cars that used to automatically limit the degrees of rotation, now go back to what you have set up on the Thrustmaster panel, without being automatic by car. It is very annoying and I don't know how to correct it. I would like to be able to use irFFB for iRacing and, sometimes, not having this problem with rFactor 2 (it also happens to me with Automobilista).
look in the controls menu for an option about dead center of the screen. I think it is called vehicle set. Make sure that box is still checked. You many have to exit after that, and double check the windows TM control panel to ensure that 900° is set there too.
Yes, I know all that. The problem I have with vjoy, is that once I install it, my TS-PC turns crazy at 1080º and as much as I mark the box you indicate, it is not corrected.She confirmed that the strike led to the termination of 100 departing and arriving flights mainly at Ryanair airport.
10:50 - 11:25 AM EDT - Attackers are Targeting Endpoint Firmware. Are You Ready?
As enterprise security improves, attackers are seeking new methods to subvert traditional security controls - going below the surface to penetrate vulnerable firmware and hardware components inside today's servers, laptops and networking equipment. In the past year APT and ransomware threat actors targeted enterprise VPNs en masse, the widespread BootHole vulnerability put virtually all Windows and Linux devices at risk for bootkits, TrickBot added firmware-specific capabilities and the Sunburst attack exposed pervasive risks in the technology supply chain. To keep pace, organizations and auditors must incorporate firmware security into risk management and compliance processes and address blind spots that have given attackers a new foothold. You'll leave this presentation with a checklist for assessing firmware security risk mapped to NIST standards.
The lethal combination of the expanding attack surface and the increased sophistication of threats present a real and present danger to many organizations. In a recent survey, more than half of CISO's stated that users' work devices are very or extremely challenging to defend. What if you can radically simplify your approach to threat response overall in today's hybrid if not largely remote working environment?
Having a robust cloud security as your first line of defense and endpoint security as your last line of defense create a powerful combination of effective, automated, always-on security that works everywhere your users go, both on and off the corporate network. What's more, when this combination comes with the cloud-native, built-in security platform that enables eXtended Detection and Response (XDR), you can protect your endpoints better, faster, and with less effort.
Join Cisco security expert Eric Howard as he demonstrates how this XDR enabled combination delivers a much simpler and more effective solution that's available today.
MITRE ATT&CK has quickly become one of the most popular frameworks for understanding and, in turn, addressing risk. However, its not immediately obvious how to use this free and powerful tool to improve security posture.
In this presentation, Michael Gorelik will provide actionable steps on how to use ATT&CK to understand the techniques that threat actors are most likely to employ when targeting businesses like yours.
Once the threats are known, it becomes clear what controls are needed to thwart them. Michael will walk through how MITRE ATT&CK can help prioritize what improvements can be made to reduce the most risk, highlighting those that dont require your business to spend more money on tools.
Finally, this presentation will explore the differences between Tactics and Techniques within the current ATT&CK framework and expand on the benefits of focusing on prevention of tactics for coverage of the most techniques.
How to use MITRE ATT&CK to understand the techniques that will most likely be used against your business specifically.
What mitigation strategies are best suited to address the techniques that are most likely to be employed.
What security teams can do without spending more money to make the most impact on risk reduction.
Applying the MITRE ATT&CK framework to prevention of Tactics for maximum coverage of Techniques.
Best practices to defend against general Tactics in ATT&CK framework rather than specific Techniques used by adversaries.
Real-world cases of applying innovative technologies to prevent Tactics agnostic of the technique.
Ransomware attacker tactics are constantly shifting - sometimes drastically - In this session Greg looks at the evolution of this prolific and damaging type of attack. He'll share stories from the frontline, looking at how the criminals operate, their techniques and how you can lower your risk of becoming their next victim.
