I’m analysing the complexity of my code. From what I found online, since strings are immutable in python, a concatenation of a string and a character should be O(len(string) + 1). Now, here is my piece of code (simplified): word = "" for i in range(m): word = char_value + word return word The total … Read more
I have been trying to work on this issue for a while.I am trying to remove non ASCII characters form DB_user column and trying to replace them with spaces. But I keep getting some errors. This is how my data frame looks:
I want to find string similarity between two strings. en.wikipedia has examples of some of them. code.google has a Python implementation of Levenshtein distance.
Is there a better algorithm, (and hopefully a Python library), under these constraints:
So I’m learning Python. I am going through the lessons and ran into a problem where I had to condense a great many target.write() into a single write(), while having a "n" between each user input variable(the object of write()).
I have a string of this form
I would like to write a regex for searching for the existence of some words, but their order of appearance doesn’t matter.
In Java, I can override the toString() method of my class. Then Java’s print function prints the string representation of the object defined by its toString(). Is there a Python equivalent to Java’s toString()? For example, I have a PlayCard class. I have an instance c of PlayCard. Now: >>> print(c) <__main__.Card object at 0x01FD5D30> … Read more
So stdin returns a string of text into a list, and multiple lines of text are all list elements.
How do you split them all into single words?
Let’s say I have: action = '{bond}, {james} {bond}'.format(bond='bond', james='james') this wil output: 'bond, james bond' Next we have: action = '{bond}, {james} {bond}'.format(bond='bond') this will output: KeyError: 'james' Is there some workaround to prevent this error to happen, something like: if keyrror: ignore, leave it alone (but do parse others) compare format string with … Read more
I’m trying to remove all newline characters from a string. I’ve read up on how to do it, but it seems that I for some reason am unable to do so. Here is step by step what I am doing:
