python check if char exists in string code example

Example 1: python string contains substring

fullstring = "StackAbuse"
substring = "tack"

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

Example 2: 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")
