sys.modules['humansize'] is the humansize module which you just imported. The replacement field {0.modules[humansize]} refers to the humansize module. Note the slight difference in syntax here. In real Python code, the keys of the sys.modules dictionary are strings; to refer to them, you need to put quotes around the module name (e.g. 'humansize'). But within a replacement field, you skip the quotes around the dictionary key name (e.g. humansize). To quote PEP 3101: Advanced String Formatting, “The rules for parsing an item key are very simple. If it starts with a digit, then it is treated as a number, otherwise it is used as a string.”
sys.modules['humansize'].SUFFIXES is the dictionary defined at the top of the humansize module. The replacement field {0.modules[humansize].SUFFIXES} refers to that dictionary.
sys.modules['humansize'].SUFFIXES[1000] is a list of SI suffixes: ['KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB']. So the replacement field {0.modules[humansize].SUFFIXES[1000]} refers to that list.
-sys.modules['humansize'].SUFFIXES[1000][0] is the first item of the list of SI suffixes: 'KB'. Therefore, the complete replacement field {0.modules[humansize].SUFFIXES[1000][0]} is replaced by the two-character string KB.
