Format floats with standard json module
... do anything to floats. However loads does. So if you don't mind the extra CPU load, you could throw it through the encoder/decoder/encoder and get the right result:
>>> json.dumps(json.loads(json.dumps([.333333333333, .432432]), parse_float=lambda x: round(float(x), 3)))
'[0.333, 0.432]'

Convert dmesg timestamp to custom date format
...el timestamps in dmesg are derived from an uptime value kept by individual CPUs. Over time this gets out of sync with the real time clock. As a result, the most accurate conversion for recent dmesg entries will be based on the CPU clock rather than /proc/uptime. For example, on a particular CentOS 6...
Pointer to pointer clarification
