Pseudo code:

`get_first_name():`

 1. Set n equal to zero
 2. Loop while n is less than the length of name and the n-th character of name is not a space
 3.     Increase n by 1
 2. Return the part of name up to but not including the n-th character to the caller

`get_last_ initial():`

 1. Set n equal to the length of name minus 1
 2. While n is bigger than or equal to zero and the n-th character or name is not a space
 3. Decrease n by 1
 3. Return the part of name starting from the n+1-th character to the caller

print_username():

 1. Call get_first_name(), passing fullname, and store the first three characters in firstpart
 2. While the length of firstpart is less than three
 3.     Add an X to the end of firstpart
 4. Call get_last_name(), passing fullname, and store the first five characters in lastpart
 5. While the length of lastpart is less than five
 6.     Add an X to the end of lastpart
 7. Concatenate firstpart and lastpart, convert the resulting string to upper case and print with a helpful message

如果你想让python中的函数执行，你必须调用它们，例如，你可以添加一行

print_username(name)

到文件的末尾。
