Kent,
I know that you know far more about python than me but
is that right ?
I created file with 4 records and this code did print
them all randomly:-
import random
i = 0
while i < 10:
file = open('filename')
listcontents = file.readlines()
file.close()
lenoflist = len(listcontents)-1
x = random.randrange(0,lenoflist)
print listcontents[x], i
i = i +1
While although this code below does work many times
nothing is printed out.
import random
i = 0
while i < 10:
file = open('test.rantxt')
listcontents = file.readlines()
file.close()
lenoflist = len(listcontents)#-1
x = random.randrange(0,lenoflist)
print listcontents[x], i
i = i +1
