Python Tasks

The following programs clearly explain the concept of indentation and highlight common mistakes we usually make.
1.expected output is "1 1 1 1 1"

program:
count = 1
while count<=5:
print(1, end=' ') #print(1, end='\n')
count=count+1

output:
1 1 1 1 1

What happens in this program?

Initially, the variable count is assigned the value 1

The while loop checks whether count is less than or equal to 5

If the condition is true, the loop executes

Inside the loop, the value 1 is printed followed by a space

After printing, the value of count is increased by 1

Now count becomes 2, and the loop runs again

This process continues until count becomes greater than 5

When count becomes 6, the condition becomes false, and the loop stops

Output
1 1 1 1 1

Additional Note

If you use:

print(1, end='\n')

The output will be:

1
1
1
1
1

Program 1
Expected Output
2 4 6 8 10 6 12
Program
count = 1
while count <= 5:
print(count * 2, end=' ')
count = count + 1

print(count, end=' ')
print(count * 2)
Explanation

Initially, count is assigned the value 1

The loop runs while count <= 5

Inside the loop, count * 2 is printed with a space

After each iteration, count is increased by 1

When the loop ends, count becomes 6

After the loop:

print(count, end=' ') prints 6
print(count * 2) prints 12
Output

2 4 6 8 10 6 12

Program 2
Expected Output
2 4 6 8 10 6
12
Program
count = 1
while count <= 5:
print(count * 2, end=' ')
count = count + 1

print(count)
print(count * 2)
Explanation

The loop works the same as in Program 1

After the loop ends, count = 6

print(count) prints 6 and moves to the next line

print(count * 2) prints 12 on a new line

Output
2 4 6 8 10 6
12
Important Concept: Indentation

If indentation is not handled correctly, the output will be unexpected.

Wrong Program
count = 1
while count <= 5:
print(count * 2, end=' ')
count = count + 1
print(count)
print(count * 2)
What happens?

The last two print statements are inside the loop because of indentation

So they execute in every iteration

This produces repeated and mixed output

Output
2 2
4
4 3
6
6 4
8
8 5
10
10 6
12
Final Key Points

Indentation decides whether code is inside or outside the loop
end=' ' prints in the same line
end='\n' prints in the next line
print() moves to the next line
Always align indentation carefully
