Python For Loop increment Tricky Example

In this post, I have explained tricky for loop example in Python. The usage of FOR LOOP is to create loops. How many times the loop will execute you may supply in the input.

My Project is to get each character from the input String. I use for loop to achieve this.
Tricky FOR LOOP Examples Explained different for loop examples.
1. Python For Loop Syntax using Variable or Array >> for valuein variable
Python For Loop Example >> myName = 'srinimf'

>> for valuein myName
...        print(value)

The result is as follows:
s
r
i
n
i
m
f
2. Python For Loop With '1' to '10' or 'n'for(i=1;i<=10;i++)<loopbody> The above for loop useful to create definite loop. The maximum loops are '10'. You can write your logic for each value in Python.

This is one of the tricky and most popular example.
3. How does a Python For Loop works a Flowchart

The 'letter' contains ValuestateName is an Array or VariableAfter For Loop you can use BODY s…

SQL top ideas on how to use built-in functions correctly

In this post I am giving top examples on SQL functions. About built-in functions, I have covered in my previous post.
sql examples on built-in functions

List of Built-in Functions

  1. DATE-TIME functions
  2. Numeric functions
  3. Char functions
  4. Null-related functions

1. DATE/TIME functions

SELECT p_code, launch_dt, CURRENT_DATE FROM product;
CURRENT_DATE returns current date.

SELECT p_code, TO_CHAR(launch_dt, 'DD MONTH YYYY') reformatted_dt FROM product;
TO_CHAR function returns DATE in CHAR format.

2. Numeric functions

SELECT p_code, price, (price - 20), ABS(price - 20.00) FROM product;
ABS - function returns absolute value

SELECT p_code, price, ROUND (price, 1) FROM product;
ROUND function - Round to 1 digit.

SELECT p_code, price, SIGN(price - 15) FROM product;
SIGN function - It returns sign; either + or -

SELECT p_code, price, TRUNC(price, 1) FROM product;
TRUNC function - Truncates to a certain number of decimal places.

3. CHAR functions

SELECT p_code, CONCAT(CONCAT(p_name, ' -- ') , price) FROM product;
CONCAT function - concats two strings.

SELECT p_name, LOWER(p_name), UPPER(p_name) FROM product;
UPPER function returns upper case.
LOWER function returns lower case.

SELECT p_name, LENGTH(p_name) FROM product;
LENGTH function returns length of the string.

SELECT SUBSTR(phone, 3) FROM customer;
SUBSTR function returns sub string from main string.

4. Null related functions

SELECT p_name, price, min_price,
COALESCE((price * 0.9), min_price, 5.0) sale_price FROM product;

COALESCE function: returns first non-null value from the expression.

Summary
  • Given list of top built-in functions
  • Example SQL queries on built-in function given for you to read quickly
  • These examples are almost common in any RDBMS
