What is the value of x after this sequence of instructions is carried out?

x=0
for i in range(10):
x=x+1

in python programming language

Answer 1

Answer :- 10

x=0

for i in range(10):

x=0+1 = 1

for i in range(10):

x=1+1 = 2

for i in range(10):

x=2+1 = 3

for i in range(10):

x=3+1 = 4

Continuing on...

for i in range(10):

x=8+1 = 9

for i in range(10):

x=9+1 = 10

Now it break out of this till when x = 10.

Answer 2

First control structure and computer starts as first line.

It goes down from there and control structures change the order that statements are executed or decide if a certain statement will be run.

a = 0

while a < 5:

   a += 1 # Same as a = a + 1

   print (a)

Decision statements also influence and whether or certain statement will run and the source for a program that uses the while control structure:

Here is the output:

2

3
