Python：去除列表括号并将十六进制内容拆分为4个元素

Got it, let's walk through how to turn your input list into the desired hex-formatted output. Here's a straightforward approach with clear breakdowns:

Step-by-Step Breakdown: #

• Pull out the raw string: Your input list has just one element, so we start by accessing that string directly.
• Clean up the formatting: Strip off the square brackets and any extra whitespace from the start/end of the string to get a clean sequence of hex pairs.
• Split into individual hex pairs: Split the cleaned string into a list of 2-character hex values using spaces as separators.
• Group into 4-pair chunks: We need 4 hex pairs to form each 32-bit value, so we slice the list into chunks of 4 elements each.
• Convert to target format: For each chunk, join the 4 pairs into a single hex string. Depending on whether you want integer values or formatted 0x strings, you can convert or format accordingly.

Code Implementation: #

If you want a list of integers (represented with 0x literals when displayed):

input_list = [' [00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 10]']

# Clean the string: remove brackets and leading/trailing whitespace
clean_hex_str = input_list[0].strip().strip('[]')

# Split into individual 2-character hex pairs
hex_pairs = clean_hex_str.split()

# Group pairs into chunks of 4
hex_chunks = [hex_pairs[i:i+4] for i in range(0, len(hex_pairs), 4)]

# Convert each chunk to a hex integer
output_list = [int(''.join(chunk), 16) for chunk in hex_chunks]

# To view with full 8-digit 0x formatting:
print([f"0x{num:08x}" for num in output_list])
# Output: ['0x00000000', '0x00000000', '0x00000000', '0x00000010']

If you want a list of formatted strings matching exactly the 0x00000000 style:

input_list = [' [00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 10]']

clean_hex_str = input_list[0].strip().strip('[]')
hex_pairs = clean_hex_str.split()
hex_chunks = [hex_pairs[i:i+4] for i in range(0, len(hex_pairs), 4)]

output_list = [f"0x{''.join(chunk)}" for chunk in hex_chunks]
print(output_list)
# Output: ['0x00000000', '0x00000000', '0x00000000', '0x00000010']

Either approach will get you exactly the result you're looking for.
