用Python创建bin文件并查看

使用pycharm写一个创建bin文件的脚本

import numpy as np

# 数据
data = np.array([0x33, 0x34, 0x34, 0x34], dtype=np.uint8)

# 指定文件路径
file_path = (r'C:\Users\JK\Desktop\example1.bin')

# 保存为bin格式
with open(file_path, 'wb') as file:
    data.tofile(file)

print("ok")

用vscode查看

使用vscode以16进制方式查看bin文件内容_vscode打开bin文件-优快云博客

安装Hex Editor,插件，快捷键ctrl+shift+p，输入hex。可以查看文件的内容

注：下面补充一个自动创建bin文件的gui的界面

import sys

from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QLineEdit, QPushButton, QVBoxLayout, QHBoxLayout, QFileDialog, QMessageBox
# gui界面，创建bin文件

        layout.addWidget(self.content_input)

            QMessageBox.warning(self, '警告', '请填写所有字段')
            return

        try:
