Final answer:
To write a Python function that writes a user input string in vertical order, you can iterate through each character of the string and print them individually on separate lines.
Step-by-step explanation:
To write a Python function that writes the user input string in vertical order, you can iterate through each character of the string and print them individually on separate lines. Here's an example:
def vertical_order(string):
for char in string:
print(char)
In this function, the string parameter represents the user input you want to write vertically. Each character of the string is printed on a separate line using the print() function.
