You can use re.sub:

In [5]: re.sub('_+', '_', s)
Out[5]: 'Hello_my_beautiful_friends!'

This uses re.sub(patter, replacement, string) where _+ indicates one ore more _ and to replace it with a single underscore.

In this way

my_string = "Hello__my_beautiful___friends!"
while "__" in my_string:
   my_string = my_string.replace("__","_")

Notice that the loop is needed since you may have consecutive "__" to remove and you do that with multiple iterations
