As pointed out in a comment from AlexP, you did not include the / at the beginning. Even if you did that, you would still not succeed. You are trying to change directory cd to a file. Type

ls -l /usr/bin/python3.7

The output should be something like that

-rwxr-xr-x 2 root root 4464400 nov 28 2017 /usr/bin/python3.5

For a directory you see a letter d at the beginning of the line, like this

drwxr-xr-x 2 root root 90112 aug 7 06:49 bin

You will see, that python3.7 is a file not a directory. You can change to a directory

cd /usr/bin

but not to a file like /usr/bin/python3.7.
