How can Python output numbers in order?

In Python, you can use a for loop to sequentially output numbers. By setting the starting and ending values of the loop, you can control the range and order of the output numbers. Here is a simple example:

for i in range(1, 10):   # 从1开始，输出到9（不包括10）
    print(i)

This code will output numbers 1 to 9, with each number on a separate line. Depending on specific requirements, you can modify the starting and ending values to output numbers within a different range.

Furthermore, if you want to output the numbers in reverse order, you can use the step parameter of the range function and set it to a negative number. For example:

for i in range(10, 0, -1):   # 从10开始，递减到1（不包括0）
    print(i)

This code will output numbers from 10 to 1, with each number on a separate line.
