Python饼图绘制：周繁忙度统计 - 解决NameError错误

Python饼图绘制：周繁忙度统计 - 解决NameError错误/n/n本文将详细介绍如何使用Python绘制周繁忙度统计饼图，并解决代码中出现的NameError: name 'get_week_number' is not defined错误。/n/n代码示例：/n/npython/nWEEK_VALUE = [WEEK1, WEEK2, WEEK3, WEEK4, WEEK5, WEEK6, WEEK7]/nplt.title(/'周繁忙统计/')/n/n# 绘制饼图/nplt.pie(WEEK_VALUE, labels=WEEK, autopct='%1.1f%%')/nplt.axis('equal') # 使饼图长宽相等/n/n# 显示图例/nplt.legend(loc=/'upper right/', fontsize=10, bbox_to_anchor=(1.1, 1.05), borderaxespad=0.3)/n/nplt.show() # 显示图表/n/n/n错误信息:/n/n/n---------------------------------------------------------------------------/nNameError Traceback (most recent call last)/n~/AppData//Local//Temp//ipykernel_8160//435641592.py in <module>/n----> 1 fmtj(pi_table)/n/n~/AppData//Local//Temp//ipykernel_8160//3456754912.py in fmtj(pi_table)/n 17 for fmdf in fmdfs:/n 18 # 获取数据对应的星期几/n---> 19 week_number = get_week_number(fmdf[1])/n 20 /n 21 # 根据星期几进行统计/n/nNameError: name 'get_week_number' is not defined/n/n/n错误原因：/n/n报错信息显示NameError: name 'get_week_number' is not defined，说明get_week_number函数没有定义。你需要在代码中定义get_week_number函数，以便在fmtj函数中调用它。/n/n解决方法：/n/n1. 定义get_week_number函数：/n/n python/ndef get_week_number(date):/n # 根据日期获取星期几的逻辑/n # .../n return week_number/n/n/n2. 根据你的业务逻辑实现get_week_number函数：/n/n 你需要根据你使用的日期格式和所需逻辑来实现get_week_number函数。例如，你可以使用Python的datetime库来获取日期的星期几。/n/n3. 确保在调用get_week_number函数之前进行定义：/n/n 确保get_week_number函数的定义位于调用它的代码之前，或者使用import语句导入包含函数定义的模块。/n/n示例：/n/npython/nimport datetime/n/ndef get_week_number(date_str):/n /'/'/'/n 根据日期字符串获取星期几的数字。/n/n Args:/n date_str: 日期字符串，例如 '2023-10-26'。/n/n Returns:/n 星期几的数字，1代表星期一，7代表星期日。/n /'/'/'/n date_obj = datetime.datetime.strptime(date_str, '%Y-%m-%d')/n week_number = date_obj.weekday() + 1/n return week_number/n/n/n注意：/n/n* 请确保你的代码中已经定义了WEEK1, WEEK2, WEEK3, WEEK4, WEEK5, WEEK6, WEEK7 和 WEEK 变量。/n* 你需要根据你的实际情况修改代码，并确保所有依赖的库和变量都已定义。/n
