[issue26022] string.replace(' ', ' ') has to be called 2 times before it works

[Ethan Furman]

Ethan Furman added the comment:

The .replace() method is not recursive (it only makes one pass through the 
string), so for example:

>>> example = '   '  # three spaces
>>> example = example.replace('  ', ' ')  # replace two spaces with one space
>>> example  # should be two spaces
'  '  
>>> example = example.replace('  ', ' ')  # replace two spaces with one space
>>> example  # should be one space
' '

This is unlikely a problem as you are using replace the send time on new string 
object.

Could you provide us with a sample file that demonstrates this behaviour?

New submission from Roland Eichman:

Windows 10 
python 3.5
small function in a small module 
contained a string len(str1) == 5000 {approx}
str1 = str1.replace('  ',' ')
did not work
added, via copy & paste, a second identical line
str1 = str1.replace('  ',' ')
str1 = str1.replace('  ',' ')
AND IT WORKED
