Write a program in Python to generate an even (length) series of random four-digit pin. Get the length from user and ask until it’s valid
The result for generating even length random four-digit pin numbers as,
enter the series size 4 Random four digit pin number series 0 0813 1 7218 2 6739 3 8390
To solve this, we will follow the steps given below −
Solution
Create an empty and list and set result as True
Set while loop and get the size from the user
Set if condition to find the size is even or odd. If the size is odd then assign the result as False and runs the loop until an even number is entered.
l = []
while(True):
size = int(input("enter the series size"))
if(size%2==1):
result = FalseIf the size is an even value then assign the result as True and set it for loop to access the range of size.
result = True for i in range(size):
Generate random four-digit numbers and store it rand_pin.
Append rand_pin values to the list then generate a series.
rand_pin = random.sample(num,4)
l.append("".join(rand_pin))
pd.Series(l)If the result value is True the break the look using if condition.
if(result==True): break
Example
Let’s understand the below code −
# importing pandas as pd
import pandas as pd
import random,string
num = string.digits
result = True
l = []
while(True):
size = int(input("enter the series size"))
if(size%2==1):
result = False
else:
result = True
for i in range(size):
rand_pin = random.sample(num,4)
l.append("".join(rand_pin))
series = pd.Series(l)
print("Random four digit pin number series\n",series)
if(result==True):
breakOutput
enter the series size 3 oops! enter an even number! enter the series size 5 oops! enter an even number! enter the series size 4 Random four digit pin number series 0 0813 1 7218 2 6739 3 8390 dtype: object
