SyntaxError：解析时出现意外的EOF

Question

运行这部分代码时出现错误。尝试了一些现有的解决方案，但都没有帮助

elec_and_weather = pd.read_csv(r'C:\HOUR.csv', parse_dates=True,index_col=0)
# Add historic DEMAND to each X vector
 for i in range(0,24):
    elec_and_weather[i] = np.zeros(len(elec_and_weather['DEMAND']))
    elec_and_weather[i][elec_and_weather.index.hour==i] = 1
# Set number of hours prediction is in advance
n_hours_advance = 24

# Set number of historic hours used
n_hours_window = 24

for k in range(n_hours_advance,n_hours_advance+n_hours_window):
    elec_and_weather['DEMAND_t-%i'% k] = np.zeros(len(elec_and_weather['DEMAND']))'

我总是收到这个错误

for i in range(0,24):
File "<ipython-input-29-db3022a769d1>", line 1
for i in range(0,24):
                     ^

SyntaxError: unexpected EOF while parsing

Answer 1

这SyntaxError: unexpected EOF while parsing意味着在完成所有代码块之前，已到达源代码的末尾。代码块以类似如下的语句开头，for i in range(100):然后至少需要一行包含其中应包含的代码的行。

好像您在ipython控制台中逐行执行程序。这适用于单个语句a = 3，例如for循环，但不适用于代码块。请参见以下示例：

In [1]: for i in range(100):
  File "<ipython-input-1-ece1e5c2587f>", line 1
    for i in range(100):
                        ^
SyntaxError: unexpected EOF while parsing

为避免此错误，您必须将整个代码块作为单个输入输入：

In [2]: for i in range(5):
   ...:     print(i, end=', ')
0, 1, 2, 3, 4,
