I am new to python and struggling with 2 simple sets of code in which there is while loop used with a little difference (atleast in my opinion). These code should print ‘i’ while it is less than 6 but one set of code is printing ‘1 2 3 4 5 6’ and the other is printing ‘0 1 2 3 4 5’. I’m not sure why there is the difference. Any help will be much appreciated. Code is below:
this code is printing: ‘1 2 3 4 5 6’:
i=0 while i<6: i+=1 print(i)
this code is printing: ‘0 1 2 3 4 5’:
i=0 while i<6: print(i) i+=1

Answer
In the first example, you are incrementing i
before you print the value:
In the second example, however, you print the value of i
first, and then increment it. That means, in the very first iteration, 0
is printed first instead of 1. Similarly, the last iteration will print a 5
since the value of i
is incremented to 6
afterwards, and the while loop breaks.
Hopefully this helped! Please let me know if you have any further questions or need any clarification :)
