system('cls') to clear the screen. The output window will print the given text first, then the program will sleep for 4 seconds and then screen will be cleared and program execution will be stopped.
To print on the same line in Python, add a second argument, end=' ', to the print() function call. print("It's me.")

Just use CR to go to beginning of the line.
import time
for x in range (0,5):
b = "Loading" + "." * x
print (b, end="\r")
time.sleep(1)
One way is to use ANSI escape sequences:
import sys
import time
for i in range(10):
print("Loading" + "." * i)
sys.stdout.write("\033[F") # Cursor up one line
time.sleep(1)
Also sometimes useful (for example if you print something shorter than before):
sys.stdout.write("\033[K") # Clear to the end of line
import sys
import time
a = 0
for x in range (0,3):
a = a + 1
b = ("Loading" + "." * a)
# \r prints a carriage return first, so `b` is printed on top of the previous line.
sys.stdout.write('\r'+b)
time.sleep(0.5)
print (a)
Note that you might have to run sys.stdout.flush() right after sys.stdout.write('\r'+b) depending on which console you are doing the printing to have the results printed when requested without any buffering.
