There is no need for you to iterate over anything. Praw provides a method which allows you to grab a random submission from a subreddit. Documentation: random() Code: Note: I have move the random_submission inside the If-statement because there is no need for you to look up a submission if the message doesn’t say “meme”. … Read more
You can achieve desired output from following code use anim_delay to delay the animation
Yes, it was added in version 2.5. The expression syntax is: First condition is evaluated, then exactly one of either a or b is evaluated and returned based on the Boolean value of condition. If condition evaluates to True, then a is evaluated and returned but b is ignored, or else when b is evaluated … Read more
How do I declare an array in Python? I can’t find any reference to arrays in the documentation.
For a meaningful interpolation, you would first need to define a 2D inperpolation function (bilinear, bicubic). For better resutls directly use the scipy implementations of the percent point function (i.e. the inverse cumulative distribution function). Result is v: 2.57058 so the result is the same as the 2.571 from your table. This code reproduces your … Read more
The enumerate() function adds a counter to an iterable. So for each element in cursor, a tuple is produced with (counter, element); the for loop binds that to row_number and row, respectively. Demo: By default, enumerate() starts counting at 0 but if you give it a second integer argument, it’ll start from that number instead: … Read more
You can read about the changes in What’s New In Python 3.0. You should read it thoroughly when you move from 2.x to 3.x since a lot has been changed. The whole answer here are quotes from the documentation. Views And Iterators Instead Of Lists Some well-known APIs no longer return lists: […] map() and filter() return iterators. If … Read more
Suppose you are designing a new class with some methods that you don’t want to implement, yet. If you were to leave out the pass, the code wouldn’t run. You would then get an: To summarize, the pass statement does nothing particular, but it can act as a placeholder, as demonstrated here.
You can make use of the reversed function for this as: Note that reversed(…) does not return a list. You can get a reversed list using list(reversed(array)).
The effects of the three different methods to remove an element from a list: remove removes the first matching value, not a specific index: del removes the item at a specific index: and pop removes the item at a specific index and returns it. Their error modes are different too:
