Python:如何计算文本文件中的平均行长

def calculate_average_line_length(file_path):
    total_length = 0
    line_count = 0

    with open(file_path, 'r') as file:
        for line in file:
            line_length = len(line.strip())  # 去除行尾的换行符并计算行长
            total_length += line_length
            line_count += 1

    if line_count > 0:
        average_length = total_length / line_count
        return average_length
    else:
        return 0

file_path = 'path/to/your/file.txt'
average_length = calculate_average_line_length(file_path)
print("Average line length:", average_length)
