I am new to python programming I was trying to check if a letter is lowercase in python. I wrote some code to check this statement :

import string

def LowerCase(s_str):
    for x in s_str:
        if x not in string.LowerCase:
            return False
    return True

But it always throw error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'UUU' is not defined
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'LoWWE' is not defined

What should I do now?

The error you are having beacuse your strings are not defined .

You can use islower to get an exact result:

def LowerCase(string):
    words=[charecter for charecter in string if charecter.islower()]
    if len(words)==len(string):
        print('All charecters are in lowercase')
        print("All charecters are not in lowercase")

strings=['LoweR', 'CASE', 'UpperCASE', 'LOWERcase']
for x in strings:

Hope this may help you.

Why can't I perform arithmetic operations on a set. For example: {a+b} * c returns an error. When we try to do [a+b]*c, it returns a list. For instance: [4+5]*6 returns [9, 9, 9, 9, 9, 9]. But the same is not the result for the set. Why?

I saw this code to find difference between diagonal sums of a square matrix. #!/bin/python3 import math import os import random import re import sys def diagonalDifference(arr): d1=0 d2=0 a=n-1 print(arr[1][1]) for i in range(0,n): d1+=arr[i][i] ... ['OUTPUT_PATH'], 'w') with fptr = sys.stdout, the output shows no difference. What then is the difference between functions of these two statements?

Problem: I have a list of arbitrary length and I need to split it into chunks of the same size and process it. There are some obvious ways to do this, like keeping a counter and two lists, and when the second list is full, add it to the first ... of any length, for example using generators. I've searched for something useful in itertoolsbut couldn't find anything useful. I may have missed this.

I got a list of numbers in the range 0-1023. I want to convert them to integers such that 1023 maps to -1, 1022 maps to -2 etc.. while 0, 1, 2, ....511 remain unchanged. I came up with this: def convert(x): return (x - 2**9) % 2**10 - 2**9 is there a more better way?
