如何为变量赋值非字符串值？Python SSL位或赋值报错求助

Hey there! Let's break down why that error is popping up and get your code working smoothly.

Why the Error Happens #

The core issue here is that you’re storing string versions of the SSL options in your list, not the actual integer constants the ssl module relies on.

When you write 'ssl.OP_NO_TLSv1_1', that’s just plain text—Python doesn’t recognize it as the actual option value. The context.options |= ... operation needs an integer (or ssl.Options type) to perform the bitwise OR, so passing a string triggers that TypeError.

How to Store & Use Real SSL Options #

Instead of storing strings, you can directly save the ssl module’s constant values in your list or dictionary. Here are a few clean, readable approaches:

1. Store Constants Directly in a List

This keeps things simple while retaining readability:

import ssl

# Store the actual SSL option constants, not their string names
noTLS = [
    ssl.OP_NO_SSLv2,
    ssl.OP_NO_SSLv3,
    ssl.OP_NO_TLSv1,
    ssl.OP_NO_TLSv1_1
]

# Initialize your SSL context
context = ssl.create_default_context()

# Now this works perfectly!
context.options |= noTLS[3]

2. Use a Dictionary for Named References

If you want to reference options by descriptive names (for even clearer code), use a dictionary to map names to the constants:

import ssl

noTLS_map = {
    "disable_ssl_v2": ssl.OP_NO_SSLv2,
    "disable_ssl_v3": ssl.OP_NO_SSLv3,
    "disable_tls_v1": ssl.OP_NO_TLSv1,
    "disable_tls_v1_1": ssl.OP_NO_TLSv1_1
}

context = ssl.create_default_context()
# Reference by name for instant clarity
context.options |= noTLS_map["disable_tls_v1_1"]

3. Enable Multiple Options at Once

If you want to disable several old protocols in one go, you can either combine them with bitwise ORs or loop through your list:

# Combine options directly in one line
context.options |= ssl.OP_NO_SSLv2 | ssl.OP_NO_SSLv3 | ssl.OP_NO_TLSv1 | ssl.OP_NO_TLSv1_1

# Or loop through your list to apply all options
for option in noTLS:
    context.options |= option

Key Takeaway #

The ssl.OP_* values are integer constants under the hood—storing them as strings strips away their actual functionality. By saving the constants themselves, you let Python use them correctly for bitwise operations with context.options.
