Python- How to check if a word has lower and uppercases

I working on a school project. I am confused on how to make the ( if ) statement detect a character with upper and lower cases. I have tried to use 'and' in an if statement but it would be too long. My current input is:

a=input('Line: ')
if 'robot' in a:
 print('There is a small robot in the line.')
elif ('robot'.upper()) in a:
 print('There is a big robot in the line.')
elif b in a:
 print('There is a medium robot in the line.')
else:
 print('No robots here.')

Don't mind the (b) I was just figuring out something I don't know how to explain. An Output example I am looking for goes like:

There is a "robot" in the line
then it would print
'There is a robot in the line'

The program will check for both upper and lowercase characters. If an input had all caps, it would print out There is a big robot in the line If an input had just lowercase letters then it would just print there is a small robot in the line. If an input with both lower and upper cases it would print: There is a medium robot in the line.

Try this:

words=["robot","ROBOT","ROBot","APPLE","Nuts"]
res=["UPPER" if w.isupper() else ("LOWER" if w.islower() else "MIXEDCASE") for w in words]  
print(res)

Output:

['LOWER', 'UPPER', 'MIXEDCASE', 'UPPER', 'MIXEDCASE']

You want to use not islower() and not isupper() to get the mixed string check. Here is the code which works!

    a=input('Line: ')
    if 'robot' in a:
        print('There is a small robot in the line.')
    elif ('robot'.upper()) in a:
        print('There is a big robot in the line.')
    elif not a.islower() and not a.isupper():
        print('There is a medium robot in the line.')
    else:
        print('No robots here.')

How about using re with IGNORECASE to check the (b) situation. It means match the words like 'robot','Robot','rObot'... 

import re

def check_robot(s):
    if re.search(r"robot", s):
        print("There is a small robot in the line.")
    elif re.search(r"ROBOT", s):
        print("There is a big robot in the line.")
    elif re.search(r"robot",s,re.IGNORECASE):
        print("There is a medium robot in the line.")
    else:
        print("'No robots here.'")

You can lowercase the input first before checking if the lowercase robot is in the input string:

Change:

elif b in a:

to:

elif 'robot' in a.lower():
