Generate a list of five-digit numerical passwords and count the number of entries that include the sequence '555'.
Question
Generate a list of five-digit numerical passwords and count the number of entries that include the sequence '555'.
Solution
Sure, here is a Python code that generates a list of five-digit numerical passwords and counts the number of entries that include the sequence '555'.
# Initialize the list and the count
passwords = []
count = 0
# Generate the passwords
for i in range(10000, 100000):
password = str(i)
passwords.append(password)
if '555' in password:
count += 1
# Print the number of passwords with '555'
print("Number of passwords with '555':", count)
This code first initializes an empty list for the passwords and a count of 0. It then generates all five-digit numbers (from 10000 to 99999), converts each number to a string, and adds it to the list. If the string contains '555', it increments the count. Finally, it prints the number of passwords that contain '555'.
