It works now ! All I had to shift the 2nd "print" statement up a few spaces and
it worked --- This is my code:
count = 0
while count < 10:
if count < 5:
print "Hello, I am an if statement and count is", count
print "Hello, I am a while and count is", count
count += 1
Output :
Hello, I am an if statement and count is 0
Hello, I am a while and count is 0
Hello, I am an if statement and count is 1
Hello, I am a while and count is 1
Hello, I am an if statement and count is 2
Hello, I am a while and count is 2
Hello, I am an if statement and count is 3
Hello, I am a while and count is 3
Hello, I am an if statement and count is 4
Hello, I am a while and count is 4
Hello, I am a while and count is 5
Hello, I am a while and count is 6
Hello, I am a while and count is 7
Hello, I am a while and count is 8
Hello, I am a while and count is 9
