Given two numbers, write a Python program to swap them.Algorithm to swap two numbersStoring the value of one variable (x) in a different variable (namely temporary - temp). Then changing the value of x by copying the value of y. Then changing the value of y by copying the value of ...

To check whether a defined variable is a string type or not, we can use two functions which are Python library functions,Using isinstance() Using type()Checking a variable is a string or not using isinstance() functionisinstance() function accepts two parameters – 1) variable name (object)...
// Swap first and second characters swap(&str[i], &str[ceilIndex]); // Sort the string on right of 'first char' qsort(str + i +1, size - i -1, sizeof(str[0]), compare); } } } // Driver program to test above function intmain() { charstr[] ="ACBC"; sortedPermutations(...
For example, if you wanted to swap two variables, the following looks cleaner than explicitly declaring a temporary variable:a, b = b, a Likewise, if a function returns multiple variables, it's cleaner to say:a, b, c = fun()
[i], i + 1, size - 1); // Swap first and second characters swap(&str[i], &str[ceilIndex]); // Sort the string on right of 'first char' qsort(str + i + 1, size - i - 1, sizeof(str[0]), compare); } } } // Driver program to test above function int main() { ...

With this setup, if you call your program with$ python main.py -ll DEBUGit will run with the logging level set to DEBUG (so all logger messages will be shown), whereas if you run it with$ python main.py -ll WARNINGit will run at the WARNING level for logging, so all INFO and ...
