I have short piece of code I'm using to print a string to the terminal one
letter at a time. It works fine when I invoke the script from within Idle;
each letter appears after the preceding one according to the designated time
interval. However if I run it in the Mac terminal ('python3 ./script.py'),
there's a pause and then the whole string prints in one go. Here's the
relevant code:
import sys
import time
text = "this text is printing one letter at a time..."
for char in text:
sys.stdout.write(char)
time.sleep(0.03)
I'm thinking this may be a tty issue (is stdout going to the right terminal?)
but I'm still finding my way and would therefore appreciate any guidance. Of
course if there's a better way of printing out one letter at a time, I'm also
interested to know that. Thanks.
P.S. if it's relevant, this is part of a simple financial maths program and
it's used to display the results after certain inputs have been gathered.
