[Python] I get an error whenever I try to read a file in Python, how can I fix this?

My code:

String = open(r"C:\Users\user\OneDrive\Documents\...\file.py", "r").read()
print(String)


I have the file stored in the exact folder, but I got an error:``

Traceback (most recent call last):
File "C:\Users\user\OneDrive\Documents\...\program.py", line 47, in <module>
VerbTo = ReadFile("VerbTo")
File "C:\Users\user\OneDrive\Documents\...\program.py", line 41, in ReadFile

FileNotFoundError: [Errno 2] No such file or directory: 'C'
