JSON Naming Convention (snake_case, camelCase or PascalCase)
1. Using camel case you lose the casing in many databases or may need special handling. For instance, Cassandra CQL is case-insensitive. If you were to map this JSON to DB records, makes sense to use snake_sase. 2. Hyphen is considered a special char in many languages and not accepted in names.
python - How do you round UP a number? - Stack Overflow
May 5, 2017 · Luckily, there is another way to do it: g = 7/5. g = int(g) + (not g.is_integer()) True and False are interpreted as 1 and 0 in a statement involving numbers in python. g.is_interger() basically translates to g.has_no_decimal() or g == int(g). So the last statement in English reads round g down and add one if g has decimal.
Python 3: UnboundLocalError: local variable referenced before ...
File "weird.py", line 5, in main. print f(3) UnboundLocalError: local variable 'f' referenced before assignment. Python sees the f is used as a local variable in [f for f in [1, 2, 3]], and decides that it is also a local variable in f(3). You could add a global f statement: def f(x): return x. def main():
What is a NullReferenceException, and how do I fix it?
The runtime throwing a NullReferenceException always means the same thing: you are trying to use a reference, and the reference is not initialized (or it was once initialized, but is no longer initialized). This means the reference is null, and you cannot access members (such as methods) through a null reference.
What is a NullPointerException, and how do I fix it?
The NullPointerException (NPE) typically occurs when you declare a variable but did not create an object and assign it to the variable before trying to use the contents of the variable. So you have a reference to something that does not actually exist. Take the following code: Integer num; num = new Integer(10);
Biggest integer that can be stored in a double - Stack Overflow
Dec 5, 2009 · The biggest/largest integer that can be stored in a double without losing precision is the same as the largest possible value of a double. That is, DBL_MAX or approximately 1.8 × 10 308 (if your double is an IEEE 754 64-bit double). It's an integer, and it's represented exactly. What you might want to know instead is what the largest integer ...
integer - What is the difference between tinyint, smallint, …
Jun 7, 2010 · So, even if you consider one of the US biggest employer such as Walmart with roughly about 2.2 million employees using an integer datatype for the employeeCount column would be unnecessary. In such a case you use mediumint (that supports from 0 to 16 million (unsigned)) for example.

This means that no, long int cannot be relied upon to store any 10-digit number. However, a larger type, long long int, was introduced ...
Find the greatest (largest, maximum) number in a list of numbers
Mar 8, 2023 · max_num = i. print(max_num) Also if you want to find the index of the resulting max, print(a.index(max_num)) Direct approach by using function max () max () function returns the item with the highest value, or the item with the highest value in an iterable. Example: when you have to find max on integers/numbers. a = (1, 5, 3, 9) print(max(a))
