Multiple Table

In a database, a table is used to store data in the form of rows and columns. Rows are aligned horizontally and identified by one or more values in a specific column. Columns are vertically aligned and identified by a unique column name.

Hi Team, Can you please help me in solving this query asap. Question- Use the python. to write a program.. The first problem has three requirements. First, write a program that will find the 450th prime number. After every 50 prime numbers in the search for the 450th, print the number of prime numbers found up to that point to the console. Include an explanation of what the iteration means (i.e., 150 prime numbers found so far). When you have identified the 450th prime number, print a statement to the console that indicates what this program was looking for and the solution. All prime numbers are odd, other than the number two. This eliminates a lot of candidates. The first step is to create an array of odd numbers, then test whether they are prime or not. Do this while you identify the remaining 449 prime numbers. You could use the modulo to test the values. How many divisors need to be checked before ruling a number out? You can review this list of prime numbers to ensure that you…
