 Write a program printing stars " * " in Printing Stars in pyramid Shape program

Explanation :

hello guys and welcome to Python

programming kriisheditz tutorials by a most

economies today in this tutorial we are

discussing about how to write programs

to get output like this that is we want

to think tasks in the pyramid shape or

triangle shape okay this is the code to

print stars in the pyramid shape here

first we are asking the user to enter

the number of rows that is for example

here we can see this star pyramid

contains 4 rows 3 is 1 2 3 and 4 right

so here num value is full so here we are

asking the user to first enter the

number of rows after that we can see the

for loop and here I is a variable and

this for loop is 4 rows okay and here we

can see the range function zero to none

suppose if we enter number of rows is 4

then brain function is 4 0 to 4 then it

will give the output as 0 1 & 2 & 3 I is

equal to 0 for this row 1 is for this so

2 is for this row and 3 is for this room

ok next in the column that is here we

can see space and start that is in some

places we need to bring space and in

some places we need to print star ok so

here we are using 2 for loop that is the

first follow - pink space and the second

for loop is to print star and here we

can see in the first for loop J is a

variable and ranges from 0 to num - I

minus 1 here we can see number Ally is 4

right and here we can see the T space

here

after that we can see the star here long

value is 4 and I value is 0 and minus 1

that will give 3

so here this statement will print price

so here we can see three space here

I value is 1 so 4 minus 1 minus 1 so it

will give 2 so we can see 2 space here I

values 2 so 4 minus 2 minus 1 so answer

is 1 so here we can see the 1 space now

after executing this statement price

control goes to the next for loop and

here we can see the range from 0 to I

plus 1 initially I value will be 0 so 0

to 1 that means it will give the value

as 0 so it will execute 1 so in the

first line we can see the fingerstyle

next it will come out of this loop and

you can print this statement that means

control goes to the next line

okay this is about the core here first

we are asking the user to enter the

number of rows then this for loop is for

growth that is 0 two numbers in the main

core look we can see 2 4 looks that is

one is for to print space and another is

to print star now we'll run this program

I'll enter number of rows is 5 and here

we can see the pyramid okay now we will

see how this code will work first we are

asking the user to enter the number of

rows for example we will take number is

4 now so control goes to this for loop I

use a variable here range 0 to num will

give 4 values again it is 0 1 2 3

fine and next it will go to the J loop

and here range is from 0 to num - I

minus 1 actually number give us 4 and

here I value 0 so 4 minus 0 minus 1 so

it will you 3 so he arranges from 0 to 3

so it will give the answer as 0 1 & 2

right so first J value will be 0

one two so here it will print space and

again be control goes to the for loop

now say value will be one and again this

print statement will execute so again

space again the control goes to the J

loop now J value is two so again it will

clean space now control is here now

control comes out of this loop and it

will go to the next for loop that ranges

from zero to I plus 1 so I'll and u is 0

so 0 to 1 that means it will give value

as 0 so here J value will be 0 so it

will go to the print statement and it

will print star here but here range

gives only one value it is already

executed so it will come out of this

loop and it will go to the next

statement that is print statement so

control goes to the next line here okay

next again it goes to the main power

loop and now I value is the one so again

control comes to this first for loop and

ranges from 0 to num minus I minus 1

number value was for I values one now

minus 1 so it will do too okay so here

ranges from 0 to 2 that means 0 and 1 so

it will print to space here okay after

executing this for loop it will come to

the next for loop and it will print star

here 0 to I plus 1 that means either use

1 so 0 to 2 so it will give value as 0

and 1 and so first print star so it will

print here here in deep space so here we

can see this space and again control

goes to this for loop now this day value

will be 1 and it will bring this star

and control is here now then control

come out of this loop and it will bring

pink statement so control comes

here here in this code if you change

here I change this to two star I plus 1

and I say this and on this and identify

here we can see the star pyramid here we

can see single star three star five star

seven and nine here we can see the odd

number of stars to do that we need to

change here and we can print this star

pyramid using single for loop also that

is here we can see the function pyramid

and it will take the parameter as Road

and inside the function we can see this

follow and I use the variable and ranges

from rows that means it will take zero

two rows and here we can see the print

statement that is it will print space

this much time and it will print star

this time that is this multiplication

symbol is a repeater and here plus

symbol is the concatenation symbol okay

so if you run this code and here I will

call the function from it and I'll pass

the parameter as Phi and test and we can

see the pyramid and this code is similar

to the previous one but here instead of

for loop we are using print statement

okay here if you want you can change

this to John okay now I will say this

and on this I will call the function

pyramid and us as for and here we can

see the output this is the odd number of

stuff okay back before now thank you for

watching don't forget to subscribe my

channel and we can mix last till then

take care.

Video tutorial to this program,

Program :

num=int(input("enter the number of rows :"))

for i in range(0,num):

for j in range(0,num-i-1):

print(end=" ")

for j in range(0,i+1):

print("*",end=" ")

print()

Output :

enter the number of rows :27
