[python] SyntaxError: unexpected EOF while parsing

I am getting error while running this part of the code. tried some of the existing solutions, none of them helped

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

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

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.

My syntax error was semi-hidden in an f-string

 print(f'num_flex_rows = {self.}\nFlex Rows = {flex_rows}\nMax elements = {max_elements}')

should be

 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.

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.

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

self.)

yielded nothing. Searching for

self.

yielded practically everything :-\

If I can help you avoid even a minute longer of deskchecking your code, then mission accomplished :-)

C:\Python\Anaconda3\python.exe C:/Python/PycharmProjects/FlexForms/FlexForm.py File "", line 1 (self.) ^ SyntaxError: unexpected EOF while parsing

Process finished with exit code 1

You're missing a closing parenthesis ) in print():

print('{0}+{1}={2}'.format(n1,n2,t1))

and you're also not storing the returned value from int(), so z is still a string.

z = input('?')
z = int(z)

or simply:

z = int(input('?'))

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":

Missing the body of "if","while"and"for" statement-->

root@nest:~/workplace# cat test.py
l = [1,2,3]
for i in l:
root@nest:~/workplace# python3 test.py
  File "test.py", line 3

               ^
SyntaxError: unexpected EOF while parsing

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

root@nest:~/workplace# cat test.py
l = [1,2,3]
print( l
root@nest:~/workplace# python3 test.py
  File "test.py", line 3

            ^
SyntaxError: unexpected EOF while parsing

Here is one of my mistakes that produced this exception: I had a try block without any except or finally blocks. This will not work:

try:
    lets_do_something_beneficial()

To fix this, add an except or finally block:

try:
    lets_do_something_beneficial()
finally:
    lets_go_to_sleep()

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:

print(9, not (a==7 and b==6)

Maybe this is what you mean to do:

import random

x = 0
z = input('Please Enter an integer: ')
z = int(z) # you need to capture the result of the expressioin: int(z) and assign it backk to z

def main():
    for i in range(x,z):
        n1 = random.randrange(1,3)
        n2 = random.randrange(1,3)
        t1 = n1+n2
        print('{0}+{1}={2}'.format(n1,n2,t1))

main()

1. do z = int(z)
2. Add the missing closing parenthesis on the last line of code in your listing.
3. And have a for-loop that will iterate from x to z-1
