Multilingual care about Python code?

Question

Say I had the following code -

homeDir = os.path.expanduser("~")
fullPath = homeDir + "/.config"
print fullPath

Will this code still function properly for someone, say, in Japan, in which home directory was made up of kanji?

My concern is that python does not know how to add two languages ​​together, or even know what to do with foreign characters.

Answer 1

All lines in your code from the question are bytes (a sequence of bytes). They can represent anything, including text encoded in some character encoding.

homeDir = os.path.expanduser("~") # input bytestring, returns bytestring
fullPath = homeDir + "/.config" # add 2 bytestrings 
print fullPath

print, , . , .
