Pyinstaller - invalid syntax

I am trying to use pyinstaller to package my script into an exe.
All sources indicate that the correct syntax is: pyinstaller FullClientCreator.py
When I issue this command, I get a syntax error:
pyinstaller FullClientCreator.py
File "C:\Users\DAVIDM~1\AppData\Local\Temp/ipykernel_7368/3509825318.py", line 1
pyinstaller FullClientCreator.py
^
SyntaxError: invalid syntax
I also tried it with the full path for the file, and I still get the same error:
pyinstaller "D:\Projects\ZZNew Client CreatorZZ\FullClientCreator.py"
File "C:\Users\DAVIDM~1\AppData\Local\Temp/ipykernel_7368/546891165.py", line 1
pyinstaller "D:\Projects\ZZNew Client CreatorZZ\FullClientCreator.py"
^
SyntaxError: invalid syntax
I am at a complete loss as to why this could be, so if anyone has any suggestions, I would greatly appreciate them.

Try another shell
I dont know which shell are you using but if you're using python shell sometimes its not working for python shell so try it on your cmd
pyinstaller --onefile file.py

zeppelin_ipyspark.py at apache zeppelin get SyntaxError: invalid syntax

when i running code with pyspark in apache zeppelin 0.8.1 , i get error like
java.lang.NullPointerException
at org.apache.thrift.transport.TSocket.open(TSocket.java:170)
at org.apache.zeppelin.interpreter.remote.ClientFactory.create(ClientFactory.java:51)
...
so i open all file in my folder zeppelin
and i try to running file zeppelin_ipyspark.py at D:\zeppelin-0.8.1-bin-all\interpreter\spark\python with cmd
and i get error
D:\zeppelin-0.8.1-bin-all\interpreter\spark\python>zeppelin_ipyspark.py
File "D:\zeppelin-0.8.1-bin-all\interpreter\spark\python\zeppelin_ipyspark.py", line 29
port=${JVM_GATEWAY_PORT}, auth_token=gateway_secret, auto_convert=True))
^
SyntaxError: invalid syntax
so can you help me?

#LSS zeppelin_ipyspark.py is not a standalone script.
It is invoked internally from Zeppelin's java code as part of Ipython interpreter, where the python script is processed to replace these strings(like JVM_GATEWAY_PORT etc) with actual values.

I was messing around with my Path variables and after putting the following 3 commands, every shell command I execute would return a Fatal Python error:

Does anyone how can I fix this? I am running Ubuntu 14.04.

install error or error running python file

I am running a basic Python file on Windows XP from IDLE.
The file name is assignment1.py.
The file content is:
import sys
var = 5
but when I run it, it gives the error:
Command: python assignment1.py
SyntaxError: invalid syntax
Then I tried another thing which also gave an error:
Command: which python
SyntaxError: invalid syntax
Not sure if the installation is wrong or something.
I am able to run the print command successfully:
>>> print "I am working fine"
I am working fine
Not sure of the issue. Request help.

It looks like what you are entering as the "command" is being interpreted as Python code. I mean, python assignment1.py is interpreted as Python code. The result is as expected:
$ python -c 'python assignment1.py'
File "<string>", line 1
python assignment1.py
^
SyntaxError: invalid syntax
You need to run the file in the correct way, probably via the IDLE menu or by pressing F5. You can check these questions for details:

A error about pyuic4

I'm trying to transform my ui file to .py file, but when I run pyuic4 in the shell, I get an error:
# pyuic4 main.ui > main_ui.py
File "/usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py", line 2
exec /usr/bin/python /usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py ${1+"$#"}
^
SyntaxError: invalid syntax
my os is fedora16

On Linux, pyuic4 should be a bash script that would usually be installed as /usr/bin/pyuic4.
The error
exec /usr/bin/python /usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py ${1+"$#"}
^
SyntaxError: invalid syntax
would be produced if you attempted to run that bash script with python.
However, the error message also gives the source file location as
File "/usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py", line 2
which doesn't make much sense, because that should be a python script.
Has /usr/lib/python2.7/site-packages/PyQt4/uic/pyuic.py somehow been over-written with the bash script?
Try opening that file, and also /usr/bin/pyuic4, in an editor to see what they contain.

If you want use python2, just type
python2-pyuic4 main.ui > main_ui.py
