types. This option is only valid for integer, float and complex types. For integers, when binary, octal, or hexadecimal output is used, this option adds the prefix respective '0b', '0o', or '0x' to the output value. For float and complex the ...
The first value is an array of the same length as unique_counts, where the value of each element is an integer representing which cluster that observation is assigned to. Since you used three clusters in this example, each observation is assigned to cluster 0, 1, or 2. The second value ...

int("25") is not an integer literal because the integer value is created from a string.When you write large numbers by hand, you typically group digits into groups of three separated by a comma or a decimal point. The number 1,000,000 is a lot easier to read than 1000000....
