Given a string of positive number ranging from 0 to 9, the task is to check whether the number is valid pin code or not, by using Python Regular Expression.The valid pin code of India must satisfy the following conditions. It can be only six digits.It should not start with zero.First digit of the pin code must be from 1 to 9.Next five digits of the pin code may range from 0 to 9.Pincode may or may not have one white space. It should allow only one white space, but after three digits. For example, 600064 and 600 064 are valid pincodes
Question
Given a string of positive number ranging from 0 to 9, the task is to check whether the number is valid pin code or not, by using Python Regular Expression.The valid pin code of India must satisfy the following conditions. It can be only six digits.It should not start with zero.First digit of the pin code must be from 1 to 9.Next five digits of the pin code may range from 0 to 9.Pincode may or may not have one white space. It should allow only one white space, but after three digits. For example, 600064 and 600 064 are valid pincodes
Solution
Sure, here is a Python function using regular expressions to validate the Indian pin code according to the rules you provided:
import re
def validate_pincode(pincode):
# Regular expression to match the pin code according to the rules
pattern = "^[1-9]{1}[0-9]{2}\\s{0,1}[0-9]{3}$"
# If the pin code matches the pattern, it is valid
if re.match(pattern, pincode):
return True
else:
return False
This function takes a pin code as a string and returns True if the pin code is valid and False otherwise. The regular expression used here is "^[1-9]{1}[0-9]{2}\\s{0,1}[0-9]{3}$", which matches exactly the rules you provided:
^[1-9]{1}: The pin code must start with a digit from 1 to 9.[0-9]{2}: The next two digits must be from 0 to 9.\\s{0,1}: There may or may not be a white space.[0-9]{3}$: The last three digits must be from 0 to 9. The$at the end ensures that the pin code does not have any extra characters after these six digits.

Given a string S(input consisting) of ‘*’ and ‘#’. The length of the string is variable. The task is to find the minimum number of ‘*’ or ‘#’ to make it a valid string. The string is considered valid if the number of ‘*’ and ‘#’ are equal. The ‘*’ and ‘#’ can be at any position in the string.Note : The output will be a positive or negative integer based on number of ‘*’ and ‘#’ in the input string.(*>#): positive integer(#>*): negative integer(#=*): 0Example 1:Input 1:###*** -> Value of SOutput :0 ? number of * and # are equal
