Basic While and If

Because Phyton use ident's, I have shown how these ident are use in a condition.
Be careful with thes Ident's, because Phyton do not give a spcific error-code when Your code does not work as You had intended.


import time

digit = 5

while (digit > 0):
<TAB>print("Waiting for while to run out...", digit)
<TAB>digit-= 1 <-Decrement
<TAB>time.sleep_ms(1500)
<TAB>if(digit==2):
<TAB><TAB>print("Breaking up..")
<TAB><TAB>break
<CRLF>
<CRLF>
<CRLF>
print( "While is over..\r\nDigit is ",  digit )




import time

digit = 5

while (digit > 0):
	print("Waiting for while to run out...", digit)
	digit-= 1
	time.sleep_ms(1500)
	if(digit==2):
		print("Breaking up..")
		break



print( "While is over..\r\nDigit is ",  digit )

The result is:



>>> import time
>>> 
>>> digit = 5
>>> 
>>> while (digit > 0):
...     
time            __name__        digit
...     print("Waiting for while to run out...", digit)
...     
time            __name__        digit
...     digit-= 1
...     
time            __name__        digit
...     time.sleep_ms(1500)
...     
time            __name__        digit
...     if(digit==2):
...         
time            __name__        digit
...         
time            __name__        digit
...         print("Breaking up..")
...         
time            __name__        digit
...         
time            __name__        digit
...         break
...         
...         
... 
Waiting for while to run out... 5
Waiting for while to run out... 4
Waiting for while to run out... 3
Breaking up..
>>> print( "While is over..\r\nDigit is ",  digit ,"\r\n")
While is over..
Digit is  2

Here I have used module Command:
First CTRL-E,
Then, right-click and select the Paste option.
Third press CTRL-D to finish.
Now the program is running in module.
If not, Press CTRL-C and evt. CTRL-D again.

The result is:


First press CTRL-E
>>> 
paste mode; Ctrl-C to cancel, Ctrl-D to finish
