Pincode Details Finder (Python Program)
This program takes a 6-digit pincode as input and validates whether it is correct or not. It extracts the first digit, first two digits, and first three digits to identify the region, sub-region, and district. Using predefined lists, it matches these digits to their respective names. Finally, it displays the location details if valid, otherwise shows an error message.
regions = [
"1-Delhi",
"2-Uttar Pradesh & Uttarakhand",
"3-Rajasthan & Gujarat",
"4-Maharashtra",
"5-Andhra Pradesh & Telangana",
"6-Tamil Nadu & Kerala",
"7-West Bengal & North East",
"8-Bihar & Jharkhand",
"9-Army Postal Service"
]
sub_regions = [
"11-Delhi Region",
"40-Mumbai Region",
"60-Chennai Region",
"70-Kolkata Region"
]
districts = [
"110-Delhi", "111-Delhi (North)", "112-Delhi (South)",
"400-Mumbai", "401-Mumbai (Suburban)", "402-Mumbai (West)",
"600-Chennai", "601-Tiruvallur", "602-Kanchipuram",
"700-Kolkata", "701-Kolkata (North)", "702-Kolkata (South)"
