Python does not support a character type, these are treated as strings of length one, also considered as a substring.
You can use square brackets for slicing along with the index or indices to obtain a substring.
var1 = "Guru99!"
var2 = "Software Testing"
print ("var1[0]:",var1[0])
print ("var2[1:5]:",var2[1:5])
