That is more digits than most people find useful, so Python keeps the number of digits manageable by displaying a rounded value instead >>> 1 / 10 0.1 Just remember, even though the printed result looks like the exact value of 1/10 , the actual stored value is the nearest representable binary fraction. Several examples are provided to help for clear understanding. Method #2 : Using map() + split() + list() Since the drawback of above method is that the conversion doesn’t change the datatype of the unit numbers, so if it’s desired to change the data type of number as well, it is suggested to additionally use map() to have list of strings as integers. They are defined as int, float, and complex classes in Python.
