Example 1: python string contains substring

fullstring = "StackAbuse"

if fullstring.find(substring) != -1:
    print "Found!"
else:
    print "Not found!"

Example 2: python check if character is letter

Example 3: can you look for specific characters in python

yourString = "string"

if "s" in yourString:
  print("There is an S in your string")
  
if "s" not in yourString:
  print("There is no S in your string")

# Casting to string is not needed but it's good practice
# to check for errors 

if str(myString) in str(myOtherString): 
    # Do Something
else:
	# myOtherString didn't contain myString
