数据字典中的无效字符标识符错误

Question

我正在尝试为学校的期末项目制作数据框。我已经计算了所有的数字，但是，Python 对我制作的数据字典不满意。我曾尝试将数字变成字符串，但同样的语法错误不断出现，我不确定该怎么做。

# The 10 min average PM 2.5 time in the interval of the traffic signal 

 avg_pm10_traffic_joint= {'Average Cycle Length (Min)': [2.944444, 2.888889, 2.277778, 2.166667, 2.055556],
                          'PM 2.5 (10 Min Avg)':[45.13, 42.05, 40.75, 40.14, 39.31],
                          'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.944 (Min))': [13.286, 12.379, 11.996, 11.817, 11.572‬],
                          'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.899 (Min))': [13.083‬, 12.190, 11.813, 11.636, 11.395‬],
                          'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.277 (Min))': [10.276, 9.574, 9.278‬, 9.139‬, 8.950‬],
                          'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.166 (Min))': [9.775‬, 9.108, 8.826‬, 8.694‬, 8.514‬ ],
                          'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.055 (Min))': [9.274‬, 8.641‬, 8.374‬, 8.248, 8.078‬] 
                     }

它给出：

Output: File "<ipython-input-8-a3a71d8fb5de>", line 6
'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.944 (Min))': [13.286‬, 12.379, 11.996, 11.817, 11.572‬],                                                                                                                                                             
SyntaxError: invalid character in identifier

指向错误的箭头位于 13.286 之后的第一个逗号处（我无法在邮件正文中看到箭头）。

当我查看 Vim 中的这段代码时，我定期在您的列表中看到 <202c>。这就是导致问题的原因。您可能需要使用不同的文本编辑器查看它以消除这些因素。

尝试复制这个：

avg_pm10_traffic_joint= {'Average Cycle Length (Min)': [2.944444, 2.888889, 2.277778, 2.166667, 2.055556],
    'PM 2.5 (10 Min Avg)':[45.13, 42.05, 40.75, 40.14, 39.31],
    'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.944 (Min))': [13.286, 12.379, 11.996, 11.817, 11.572
    'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.899 (Min))': [13.083, 12.190, 11.813, 11.636, 11.395
    'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.277 (Min))': [10.276, 9.574, 9.278, 9.139, 8.950
    'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.166 (Min))': [9.775, 9.108, 8.826, 8.694, 8.514],
    'Average PM 2.5 per Traffic Signal Cycle Rate (Rate = 2.055 (Min))': [9.274, 8.641, 8.374, 8.248, 8.078] 
}
