    I need to format a decimal (floating point) number in the following
    10 results in '10'
    10.5 results in '10.5'
    10.50 results in '10.5'
    10.5678 results in 10.57

    How can I achieve this using standard Python string formatting
    Something like '%.2f' works almost as expected:'10.00'
    But I always need trailing zeros to be excluded, i.e. 10.5 should
    result in '10.5' (not '10.50'), and 10 should result in '10' (not
    So how can I do this?
    Sorry for my English.
    Thanks in advance.

    with regards,

    ('%.2f' % 10).rstrip('0').rstrip('.')
