可以进一步简化代码,避免重复代码。例如:
```
def batt_cal(package):
"""battery calculation"""
switches = package['switches']
main_path, data_path, log_path, done_path = package['paths']
vin = package['FileName'].split('.')[0]
log_file = '%s_batch.log' if switches['batch_cal'] else '%s_single.log'
set_logging_level("WARNING", os.path.join(log_path, log_file % vin))
try:
batch_analysis(package) if switches['batch_cal'] else single_analysis(package)
except FileNotFoundError:
print('Error encountered: %s' % package['BattName'])
```
这样可以避免重复代码,同时更加简洁。同时,可以根据 switches['batch_cal'] 的值选择是调用 batch_analysis 还是 single_analysis 函数,避免了重复的 if/else 判断。

优化代码def parallel_cal(input_packages, cpu_count): """ 并行计算函数 :param input_packages: 输入函数参数 :param cpu_count: CPU数量 :return: """ number = 0 with concurrent.futures.ProcessPoolExecutor(max_workers=cpu_count) as executor: res = executor.map(batt_cal, input_packages) for car in zip(input_packages): print('Process %s , is No. %d' % (car, number)) number += 1 return
这段代码的问题在于,您使用了`zip`函数将`input_packages`和`executor.map(batt_cal, input_packages)`打包在一起,但`zip`函数只会返回一个元组,包含每个迭代器中相同位置的元素。因此,您的`for`循环只会遍历`input_packages`一次,而不是遍历每个并行计算的结果。因此,您需要修改代码以正确遍历每个并行计算的结果。以下是修改后的代码:
```python
import concurrent.futures
def parallel_cal(input_packages, cpu_count):
"""
并行计算函数
:param input_packages: 输入函数参数
:param cpu_count: CPU数量
:return:
"""
with concurrent.futures.ProcessPoolExecutor(max_workers=cpu_count) as executor:
futures = [executor.submit(batt_cal, package) for package in input_packages]
for number, future in enumerate(concurrent.futures.as_completed(futures)):
res = future.result()
print('Process %d is completed with result %s' % (number, res))
```
在这个修改后的代码中,我们使用`concurrent.futures.as_completed`函数来迭代已完成的并行计算,并使用`future.result()`方法获取结果。同时,我们也将`enumerate`函数用于`as_completed`迭代器,以便获取每个计算的编号。
static void battery_module_get_battery_info(void) { device_batt_info_t *p_batt = (device_batt_info_t *)store_driver_get(STORE_DATA_ID_BATT_INFO); if(p_batt->b_capacity_calibr==false) { p_batt->battery_voltage = battery_module_get_software_cal_voltage(); } g_battery_module_mgr.capacity.before_charge_persentage = battery_module_get_level_persentage(); BATT_MODULE_PRINT(" battery_persentage init (0x%x)%d%% \r\n", g_battery_module_mgr.capacity.before_charge_persentage, g_battery_module_mgr.capacity.before_charge_persentage); }
这是一段 C 语言代码,它的作用是获取电池相关信息并初始化电池电量百分比。其中使用了一个指向结构体的指针,还有一个名为 "STORE_DATA_ID_BATT_INFO" 的宏定义,可能是指存储电池信息的位置。在获取电池电量百分比时,使用了一个名为 "battery_module_get_level_persentage" 的函数。
