Generating Random Verification Codes in Python

Problem

In everyday mobile app usage, login often requires a verification code to ensure account security, and the article explores whether Python can be used to generate such random codes.

Method

Add an empty list.

Append ASCII characters (uppercase A‑Z, lowercase a‑z, digits 0‑9) to the list.

Randomly sample six characters from the list.

Join the sampled characters into a string and output it.

Through experimentation, the proposed method is shown to be effective for generating verification codes.

Code Listing 1

import random,string
li_code = []
for i in range(65,91):#大写字母A-Z
    li_code.append(chr(i))
for j in range(97,123):#小写字母a-z
    li_code.append(chr(j))
for k in range(48,58):#数字0-9
    li_code.append(chr(k))
code = random.sample(li_code,6)
ran_code = "".join(code)
print(ran_code)

Conclusion

The article presents a simple approach of creating an empty list and populating it with ASCII characters to generate verification codes, confirming its effectiveness through practice, while noting that the method does not cover front‑end integration.
