What is: this.c = 97 & this.i = 25 in 🐍 module: this ⁉️

Question

this.s /s like secret/ is encrypted text this - "The Zen of Python".
You can decrypt it using the dictionary this.d /d like decrypt/.

import this
print(this.d)
print(this.s)
print(''.join([this.d.get(x,x) for x in this.s]))

but I don't know what are: this.c & this.i ⁉️
