How to Work With Tuple in Python

Image
Tuple in python is one of the streaming datasets. The other streaming datasets are List and Dictionary. Operations that you can perform on it are shown here for your reference. Writing tuple is easy. It has values of comma separated, and enclosed with parenthesis '()'. The values in the tuple are immutable, which means you cannot replace with new values. #1. How to create a tuple Code: Tuple example my_tuple=(1,2,3,4,5) print(my_tuple) Output: (1, 2, 3, 4, 5) ** Process exited - Return Code: 0 ** Press Enter to exit terminal #2. How to read tuple values Code: print(my_tuple[0]) Output: 1 ** Process exited - Return Code: 0 ** Press Enter to exit terminal #3. How to add two tuples Code: a=(1,6,7,8) c=(3,4,5,6,7,8) d=print(a+c) Output: (1, 6, 7, 8, 3, 4, 5, 6, 7, 8) ** Process exited - Return Code: 0 ** Press Enter to exit terminal #4.  How to count tuple values Here the count is not counting values; count the repetition of a given value. Code: sample=(1, 6, 7, 8, 3, 4, 5, 6, 7, 8

How to Write Recursive Shell Script in Bash Terminal

Bash Recursive Function How to Write it Quickly


Here's a simple bash recursive function. To write it, you can use JavaScript and other scripting languages. Below is the example that shows you how to write a recursive function in the bash shell.

Recursive function

Precisely, calling the same function within it is called the Recursive function. We call itself and its contents. 

Moreover, the recursive functions go in the loop due to self-calling. While writing the code, ensure it has a condition that breaks the loop.

Recursive logic


#!/bin/bash
for ((i = 1; i < 65; i++))
{ ((arr[i - 1] = i)) } i = 1;
key = 8

function linear_search {
echo "Element value: ${arr[$i-1]}"
if ((arr[i - 1] == key)) then
echo "Linear search found $key on attempt $i" return 0 => it breaks the loop
else ((i++)) linear_search = > Calling th same script fi
}
linear_search = > Calling the same script

Output

Here is the dissection of the output. Displayed the array's elements until match-condition occurs. In the end, a display statement tells at which point the condition is satisfied.


Shell script


Summary

  • The For Loop's purpose is to get elements one by one
  • The "arr" is a keyword for an Array in bash
  • The i-1 is to calculate an index for the array
