The main problem with your format is that Python does not support anything more granular than microseconds, as explained here. In fact, assuming you have 000 as the last three decimals of seconds, you can use the format below. from datetime import datetime datetime_object = datetime.strptime(’24/NOV/18 05:15:00.000000000 AM’, ‘%d/%b/%y %I:%M:%S.%f000 %p’) If you cannot make … Read more

Use pos = my_list.index(‘asd’) nearest = my_list[pos + 1] Note pos is 3 for the 4th element as Python is 0- based. Note avoid using list for variables as this name has a special meaning in Python. 1 solved How to find the nearest element in a list [closed]

You absolutely may call a function within another function in Python, so long as the callee is in the scope of the caller. Check out this question and answer: Short Description of the Scoping Rules? The short of it: inside a function, you can call functions in the global scope, the function scope, or, if … Read more
>>> from random import randint >>> n = 10 >>> a = [0]*n // initialise array a wwith exactly n zeros >>> a [0, 0, 0, 0, 0, 0, 0, 0, 0, 0] >>> i = randint(0,n-1) // get random number from 0 to n-1 >>> i 1 >>> a[i]=n //assign a[i] to n >>> … Read more
The variable n inside the function is distinct from the expression (or variable) supplied as an argument. As such, assigning to n inside the function will not affect any of the variables outside. (This is because Python is not Call By Reference.) Instead, use the return value, eg. def classifyInput(n): if n == “r”: return … Read more
“i” is a variable used to keep track of what iteration you are on for the loop. “i” starts at 1 and each iteration is incremented by 1. The “s[i:i+3]” means “the values in s from the character at ‘i’ to the character at ‘i+3′”. 2 solved counting word instances in a string
There are a lot of issues with your code. I altered the function isPrime. There is among other no need for count here and if you want to increment test by 1 every loop use test +=1: def isPrime(value): test = 2 while(test < value): if( value % test != 0): test +=1 else: return … Read more
Load xml, traverse it (eg recursively), return tags with non-empty text. Here as generator: import xml.etree.ElementTree as ET def getNonemptyTagsGenerator(xml): for elem in xml: yield from getNonemptyTagsGenerator(elem) if len(xml) == 0: if xml.text and xml.text.strip(): yield xml xml = ET.parse(file_path).getroot() print([elem for elem in getNonemptyTagsGenerator(xml)]) Result: [<Element ‘field’ at 0x7fb2c967fea8>, <Element ‘text’ at 0x7fb2c9679048>] You … Read more
To set a default value in a function you should do like in the code bellow and you don’t have to use str to convert x to a string, just send the string. def multiply(x,mult_int=10): return x*mult_int print(multiply(“I hope that’s not your homework.\n”, 2)) print(multiply(“Bye.”)) 1 solved The function should return the string multiplied by … Read more
