Question

for i in range(0,3):
If not text[i].isdecimal():
return false

Answer 1

The line if not text[i].isdecimal(): is a conditional statement in Python that checks if the i-th character of the string text is not a decimal digit. If the condition is true, the return false statement will be executed, which will cause the function to immediately return the value False and stop executing further code.

The isdecimal() method returns True if all characters in the string are decimal characters (0-9), and False otherwise. In this case, the not operator is used to negate the result of isdecimal(), so the condition is true if the i-th character of the string text is not a decimal digit.
