I would like to make a program that will print out number values. I want it to display the number, then replace it with another number. A little like this:
val = 0
for looper in range(1, 10):
val += 1
print (val)
#Code to replace old number to new number
Thanks for helping!
If you want in-place update of the number, you can use \\r.
import sys
val = 0
for looper in range(1, 10):
val += 1
sys.stdout.write("\r%d" % (val))
sys.stdout.flush()
time.sleep(1) # sleep added so that you can see the effect
Seems like you're looking for something to replace output in sys.stdout
.
This is limited without using external libraries but you can do something like this:
import sys
import time
for number in xrange(10):
# put number in 'stdout'
sys.stdout.write(str(number))
# empty stdout (by default it waits for a new line)
sys.stdout.flush()
# display the number for some time
time.sleep(1)
# go back to beginning of input to override existing output
sys.stdout.write('\r')
我认为您正在将回车符与time.sleep(ms)一起使用“ \\ r”
On Python 3, @Teemu Kurppa's answer could be written as:
import time
for i in range(1, 11):
print(i, end='\r', flush=True)
time.sleep(1)
