checking if there are numbers in the string

[Ofnuts]

can you elaborate on,  "any(c.isdigit() for c in flyTo):"
thanks a lot

In slo-mo:

• for c in flyTo in an iterator... it iterates each element of flyTo. Since flyTo is a string the elements are characters
  
• c.isdigit() is True if c is a digit
  
• for c in flyTo builds a list of True or False, once for each character
  
• any(some list) is True if there is at least one element that evaluates to True in the list
  

So any(c.isdigit() for c in flyTo) evaluates to True is at least one character of flyTo is a digit.

A different way of doing it:

len(flyTo)!=len(flyTo.translate(None,'0123456789'))
