Resolving "typeerror: not all arguments converted ... in Python"

# Since `x` is a string, the `%` operator is treated as a string
# interpolation operator. The error occurs because no format specifier
# is provided.

if(x % 2):
  print("x is odd")

x = "11"
# This tells the compiler that % is used as the modulus operator
