math.random () generates a random decimal value between 0 and 1. The function takes no arguments. To get random numbers greater than 1, simply multiply the result as needed.
In programming, there are often times when you need to get a random number. For example, you can create a puzzle and want your program to generate a random number each time the user runs the program. Or you might want to run a function a random number of times.
One of the most useful functions in the Math library - and the one we’ll use later in this tutorial - is the Math.floor () function. This method can be used to return a value rounded to the nearest whole number or lower whole number. Here is an example of the Math.floor () method in action:
console.log (Math.floor (5.7));
Our code returns: 5. The number Math.floor () the processed function has been rounded to lower, that’s why our program returned "5" instead of "6".
Similarly, the Math.round () function can be used to round a number down closer Here is an example of the Math.round () function in action:
console.log (Math.round (5.7));
Our code returns:
Here is an example console.log () used to print a random number:
Our program returns:
As you can see, our program returned a random number between zero and one. But this number is quite small, and many applications that require random numbers want to generate larger numbers. This is where the Math.floor () function comes in.
Here is the result of our program after running it three times:
As you can see, our program generated a random number. In the example above, we used
" * 10 " to generate a larger number. This function helps us to retrieve a number between
"10." If we wanted a bigger number, we could change our multiple like this:
After running our program three times, the following numbers were generated:
So let’s say we create an addition set and we want to generate two random numbers between" 1 " and" 100 " for our additional sum to be understood. We could use the following code to generate our random numbers:
Our program returns:
What is 93 + 56 ?
In the example above, we first generated two random numbers using the Math.random () function. So, we printed a statement asking the user
" What is [our first number] + [our second number] ?"
Math.random () doesn’t include any arguments, which means we can’t use the function to generate a number between two values. However, we can create a custom method that allows us to generate a number random between two values.
Let’s say we create an addition game that should generate two numbers between 100 and 200 for one more advanced.
Here is an example of a function we could use to generate these numbers:
When we run our program three times, the following values ‚Äã‚Äãare returned:
As you can see, our program generates random numbers between 100 and 200. Let’s analyze our program and explore how it works in more depth.
In the first line, we define a function called
"generateRandomNumber ()". Our function takes two arguments: the minimum value and the maximum value of the range of numbers in which our random number is to be generated. On the next line, we use the Math.random () function to generate a random number and our
"min" variables to make sure that the number that we generate falls within our range.
So in the last line, we call our generateRandomNumber () function and pass it the values ‚Äã‚Äã100 and 200. So when we run our program, a number between 100 and 200. < br>
How to get an absolute file path in Python
Given a path such as
"mydir/myfile.txt", how do I find the file"s absolute path relative to the current working directory in Python? E.g. on Windows, I might end up with:
>>> import os
Also works if it is already an absolute path:
>>> import os
How to check if a path is absolute path or relative path in a cross-platform way with Python?
UNIX absolute path starts with "/", whereas Windows starts with alphabet "C:" or "".
Does python have a standard function to check if a path is absolute or relative?
True if the path is absolute,
False if not. The documentation says it works in windows (I can confirm it works in Linux personally).
How to join absolute and relative urls?
I have two urls:
url1 = "http://127.0.0.1/test1/test2/test3/test5.xml"
url2 = "../../test4/test6.xml"
How can I get an absolute url for url2?
