I have a string that contains many spaces. For example

x = 'test1    test2 test3    test4  test5       test6'

how can I format the string to contain only one space between the 'test' values. For example how do get it to do the following:

x = 'test1 test2 test3 test4 test5 test6'

I thought about using strtran() command but I don't it works the way I want it too.

Thanks
Nick
