<END_TASK>
<USER_TASK:>
Description:
 For this example we need to import the string library.
Step1:  Our initial example will use the uppercase letters that are in the string library.
Step2:  Here we will check to see if a letter is in the string.ascii_uppercase constant.

<ASSISTANT_TASK:>
Python Code:
import string
Explanation: For this example we need to import the string library.
End of explanation
print(string.ascii_uppercase)
Explanation: Our initial example will use the uppercase letters that are in the string library.
End of explanation
if 'b' in string.ascii_uppercase:
    print("Yes, the letter is in string.ascii_uppercase")
else:
    print("No, the string is not in string.ascii_uppercase")
Explanation: Here we will check to see if a letter is in the string.ascii_uppercase constant.
End of explanation
print(string.ascii_lowercase)
print(string.whitespace)
Explanation: Here are some other interesting constants in the string library.
