zigzag example - shabux - May-03-2020
windows 10, python 3.8
Trying to do zigzag example but not getting right result. I type following code, which I think is identical to the lesson's:
import time, sys
indent = 0 # How many spaces to indent.
indentIncreasing = True #Whether the indentation is increasing or not.
try:
while True: #The main program loop
print('' * indent, end='')
print('********')
time.sleep(0.1) #Pause for 1/10 of a second.
if indentIncreasing:
#Increase the number of spaces:
indent = indent + 1
if indent == 20:
#Change direction:
indentIncreasing = False
else:
#Decrease the number of spaces:
indent = indent - 1
if indent == 0:
#Change direction:
indentIncreasing = True
except KeyboardInterrupt:
sys.exit()But instead of getting a looping result like this: ********
********
********
********
********
********
********
********
********...I am instead getting a looping result like this:******** ******** ******** ******** ******** ******** ******** ******** ********

Hint, you will require a space in your code

'' is not ' '

I initially used " instead of '', because if I used " I get an EOL syntax error.

Is line 7 supposed to be printing spaces? I don't see any spaces on that line.
RE: zigzag example - menator01 - May-04-2020
Yes. Line 7 should have one space in the first quotes.

hello,
I am a total newb and just started learning (self-teaching Python). I, too, am having the same problem as the initial poster in here and I read your hint about a space in Line 7 but cannot, for the life in me, get it to work. I've added, taken away, and even used quotes rather than apostrophes (even though I know that's not proper coding). I've run through the debugger and looked step by step but cannot find where I'm missing a space. I couldn't find any hints after further web searches as well. May I ask for another hint, please sir (totally feel like Oliver Twist of the python world asking that)?
Thank you for your time and help!

print(' ' * indent, end='')
