How to Split a Space-Separated String into Integers in Python

To break a string of space-separated numbers into an array of integers, a simple method is to leverage string splitting and type conversion.

Splitting the String:

Use the str.split() method to separate the string into a list of substrings. By default, str.split() considers any whitespace character as a delimiter. Thus, you can simply call it without any arguments:

"42 0".split()

Alternatively, you can specify a specific whitespace character (e.g., a space) as the delimiter:

"42 0".split(" ")

Note that both approaches will split the string into ['42', '0'].

Converting to Integers:

To convert each substring into an integer, use the map() function with int as the conversion function:

map(int, "42 0".split())

In Python 2, this will return a list of integers, while in Python 3, it will return a lazy map object. To get a concrete list, you can use the list() function:

list(map(int, "42 0".split()))

This will produce the desired result: [42, 0].
