SyntaxError: unexpected EOF while parsing
提问by Akash Joshi
I am getting error while running this part of the code. tried some of the existing solutions, none of them helped
运行这部分代码时出现错误。尝试了一些现有的解决方案，但没有一个帮助
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']))'
I am always getting this error
我总是收到这个错误

The SyntaxError: unexpected EOF while parsingmeans that the end of your source code was reached before all code blocks were completed. A code block starts with a statement like for i in range(100):and requires at least one line afterwards that contains code that should be in it.
这SyntaxError: unexpected EOF while parsing意味着在所有代码块完成之前就到达了源代码的末尾。代码块以类似语句开头，for i in range(100):之后至少需要一行包含应包含在其中的代码。
It seems like you were executing your program line by line in the ipython console. This works for single statements like a = 3but not for code blocks like for loops. See the following example:
看起来您是在 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。请参阅以下示例：
In [1]: for i in range(100):
File "<ipython-input-1-ece1e5c2587f>", line 1
for i in range(100):
^
SyntaxError: unexpected EOF while parsing
To avoid this error, you have to enter the whole code block as a single input:
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,

This can simply also mean you are missing or have too many parentheses. For example this has too many, and will result in unexpected EOF:
这也可能意味着您缺少括号或括号太多。例如这有太多，会导致意想不到的EOF：
print(9, not (a==7 and b==6)

My syntax error was semi-hidden in an f-string
我的语法错误半隐藏在 f 字符串中
print(f'num_flex_rows = {self.}\nFlex Rows = {flex_rows}\nMax elements = {max_elements}')
should be
应该
print(f'num_flex_rows = {self.num_rows}\nFlex Rows = {flex_rows}\nMax elements = {max_elements}')
It didn't have the PyCharm spell-check-red line under the error.
错误下没有 PyCharm 拼写检查红线。
It did give me a clue, yet when I searched on this error message, it of course did not find the error in that bit of code above.
它确实给了我一个线索，但是当我搜索此错误消息时，它当然没有在上面那段代码中找到错误。
Had I looked more closely at the error message, I would have found the '' in the error. Seeing Line 1 was discouraging and thus wasn't paying close attention :-( Searching for
如果我更仔细地查看错误消息，我会在错误中找到 ''。看到第 1 行令人沮丧，因此没有密切关注 :-( 搜索

yielded nothing. Searching for

If I can help you avoid even a minute longer of deskcheckingyour code, then mission accomplished :-)
如果我能帮助您避免再多花一分钟的时间检查您的代码，那么任务就完成了 :-)

Here is one of my mistakes that produced this exception: I had a tryblock without any exceptor finallyblocks. This will not work:
这是导致此异常的我的错误之一：我有一个try没有任何except或多个finally块的块。这将不起作用：
try:
lets_do_something_beneficial()
To fix this, add an exceptor finallyblock:
要解决此问题，请添加一个exceptorfinally块：
try:
lets_do_something_beneficial()
finally:
lets_go_to_sleep()

elec_and_weather['DEMAND_t-%i'% k] = np.zeros(len(elec_and_weather['DEMAND']))'
elec_and_weather['DEMAND_t-%i'% k] = np.zeros(len(elec_and_weather['DEMAND']))'
The error comes at the end of the line where you have the (') sign; this error always means that you have a syntax error.
错误出现在您有 (') 符号的行的末尾；这个错误总是意味着你有一个语法错误。

There are some cases can lead to this issue, if it occered in the middle of the code it will be "IndentationError: expected an indented block" or "SyntaxError: invalid syntax", if it at the last line it may "SyntaxError: unexpected EOF while parsing"：
有一些情况会导致这个问题，如果它出现在代码中间，它会是“IndentationError: expected an indented block”或“SyntaxError: invalid syntax”，如果它在最后一行它可能是“SyntaxError：unexpected解析时的EOF”：
Missing body of “if,while or for” statement-->
缺少“if,while or for”语句的主体-->

l = [1,2,3]
for i in l:

Unclosed parentheses (Especially in complex nested states)-->
