For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Checking the type of characters entered
String Handling example from a Well House Consultants training course
More on String Handling [link]

This example is described in the following article(s):
   • Python - fresh examples from recent courses - [link]

Source code: lit Module: Y108
#!/usr/bin/env python3

""" Python's string methods such as isdigit let you check whether a string is
comprised of one type of character - in this case, a digit. Using such methods,
you can quickly check what sort of input you have from your user; here's an
example where the user is asked to enter his name or his id, and the code will
choose its follow-up action based on which was entered. """


value = input("please enter id or name: ")

if value.isdigit():
        print("id")
else:
        print("name")

print(value)

""" Sample Output

WomanWithCat:y108 grahamellis$ python3 lit
please enter id or name: 44
id
44
WomanWithCat:y108 grahamellis$ python3 lit
please enter id or name: Graham
name
Graham
WomanWithCat:y108 grahamellis$
