Define a function immPairsBool(..) which receives a string (containing letters, digits or special characters) and returns the Boolean value True if there are at least two identical characters one immediately after the other in the string. 

As an example, the following code fragment:

val = immPairsBool("123xx321")

print (val)

should produce the output:

True

Language: python

I have this so far, but doesn't work:

def immPairsBool(st):

res = ""

for k in range(len(st)-1):

if st[k]==st[k+1]:

res = "True"

if st=="":

res="False"

return res
