How does #Python crawler convert Chinese characters in the website into 16 binary strings?

Import quotation marks from urllib.parse

main_url = "/item "

Universitys = ["Beihang University", "Tsinghua", "Wuhan University", "Huazhong University of Science and Technology"].

For universities in universities:

URL = f " { main _ URL }/{ quote(university)} "

Print (url)

The results are as follows:

/item/% E5 % 8C % 97% E4 % BA % AC % E8 % 88% AA % E7 % A9 % BA % E8 % 88% AA % E5 % A4 % A9 % E5 % A4 % A7 % E5 % AD % A6

/item/% E6 % B8 % 85% E5 % 8D % 8E % E5 % A4 % A7 % E5 % A6

/item/% E6 % AD % A6 % E6 % b 1% 89% E5 % A4 % A7 % E5 % AD % A6

/item/% E5 % 8D % 8E % E4 % B8 % AD % E7 % A7 % 9 1% E6 % 8A % 80% E5 % A4 % A7 % E5 % AD % A6
