def read_log_file(file_path): """ When reading the log file and encountering 'Initialization of star.flow.', write the CSV line by line starting from the next line """ with open(file_path, 'r') as f: start_writing = False lines = [] for line in f: if start_writing: lines.append(line.strip()) if "Initialization of star.flow.EffectiveViscositySolver requires an additional pass..." in line: start_writing = True with open('output.csv', 'w') as out_file: out_file.write("\n".join(lines))这段代码的作用是什么？

这段代码的作用是读取一个名为 `file_path` 的 log 文件，并在遇到特定字符串 `"Initialization of star.flow.EffectiveViscositySolver requires an additional pass..."` 后，从下一行开始逐行将 log 文件的内容写入到一个名为 `output.csv` 的 CSV 文件中。读取的 log 文件中，如果遇到 `"My name is kitty"` 这个字符串，则会忽略该行及其之后的所有内容。其中，`strip()` 方法用于去除每一行开头和结尾的空格和换行符。
