Merge two JSON objects programmatically
I have two JSON objects here, generated through the Google Search API. The URL’s of these objects can be found below.
string-concatenation
How slow is Python’s string concatenation vs. str.join?
As a result of the comments in my answer on this thread, I wanted to know what the speed difference is between the += operator and ''.join()
String concatenation without ‘+’ operator
I was playing with python and I realized we don’t need to use ‘+’ operator to concatenate static strings. But it fails if I assign it to a variable.
Is the time-complexity of iterative string append actually O(n^2), or O(n)?
I am working on a problem out of CTCI.
Any reason not to use ‘+’ to concatenate two strings?
A common antipattern in Python is to concatenate a sequence of strings using + in a loop. This is bad because the Python interpreter has to create a new string object for each iteration, and it ends up taking quadratic time. (Recent versions of CPython can apparently optimize this in some cases, but other implementations can’t, so programmers are discouraged from relying on this.) ''.join is the right way to do this.
