2024 Nested for loop python

Here is how you would do this with a nested list comprehension: [[float(y) for y in x] for x in l] This would give you a list of lists, similar to what you started with except with floats instead of strings. If you want one flat list, then you would use. [float(y) for x in l for y in x]. Carpet cleaning austin tx

The above example is a bit basic, you can also include conditionals, or, in other words, an if condition, to make it even more customized. Take a look at the following example: # Take user input. number = 2. # Condition of the while loop. while number < 5 : # Find the mod of 2. if number%2 == 0:yield i. i += 1. print(x) It is also possible to achieve this by mutating the list you're iterating on, for example: l.append(x + 1) print(x) In Python 3, range () can go much higher, though not to infinity: pass. This will create a big loop, yes, but not an infinite loop, so I don't think it answers the question.The issue is that you're not creating voltageArray in the shape you expect, you're actually initializing it to be a list of two lists, the first inner-list has length 25, and the second inner-list has length 630.
