Question

Write a for loop that prints: 1 2 ___________ countnum. For example, if the input is 4, the output is: 1 2 3 4.

Answer 1

A for loop for printing numbers from 1 up to a given countnum can be written in Python using the range function within the loop, and setting the print function's 'end' parameter to a space.

Step-by-step explanation:

To create a for loop that prints numbers from 1 up to a specified count number in Python, you would use the following code structure:

countnum = int(input("Enter a number: "))
for i in range(1, countnum + 1):
print(i, end=' ')

This loop starts at 1 and increments the value of i by 1 on each iteration, stopping when it reaches countnum. The range function generates a sequence of numbers, which by default starts at 0. By starting at 1 (i.e., range(1, countnum + 1)), it will print numbers starting with 1 up to and including countnum. The print function includes an 'end' parameter that specifies what to print at the end of each number. Setting it to ' ' (a space) ensures that numbers are separated by spaces rather than new lines.
