python - Counting the number of iterations in a loop -

how can count number of input given user in while loop?

say user enters 50 numbers. how can count number of input.

for example,

largest_so_far =  none  smallest_so_far = "+inf"   while true:      value = raw_input(">")     if value == "done":         break      try:          value = float(value)     except valueerror:          print "invalid input"         continue      if value > largest_so_far:                   largest_so_far = value     if value < smallest_so_far:             smallest_so_far = value 

you can use simple counter :

largest_so_far =  float('-inf')  smallest_so_far = float('inf') = 0 while true:      value = raw_input(">")     if value == "done":         break      try:          value = float(value)         = + 1     except valueerror:          print "invalid input"         continue      if value > largest_so_far:                   largest_so_far = value     if value < smallest_so_far:             smallest_so_far = value 

the value of amount of inputs given user, minus done. can add moving incrementation above if.

if don't know counter is, recommend learn more before coding. how know use try statements , no counters? have done code yourself?

using code internet not problem, need understand it. :-)
