You can use the following error handlers in the str() function when using a bytes or bytearray input argument. ValueMeaning 'strict' (Default) Raise UnicodeError 'ignore' If data input would cause an error, ignore it and continue without notice. 'replace' Replace with replacement marker U+...
Send data to the socket. The socket mustbeconnected to a remote socket. The optional flags argument has the same meaning as for recv() above. Returns the number ofbytessent. Applications are responsible for checking that all data hasbeensent; if only some of the data was transmitted, the ...
The error message conveys its meaning precisely. AttributeError: 'str' object has no attribute 'DataFrame' ^ ^ ^ the kind of error | | the thing you tried to use what was missing from it The line it's complaining about: df = pd.DataFrame(date, columns = ['Date']) ...

To ensure this, the signal JRTCK is output from the STR91xFA and is input to the external JTAG test equipment to hold off transitions of JTCK until the CPU core is ready, meaning that the JTAG equipment cannot send the next rising edge of JTCK until the equipment receives a rising edge...
Whenever we writea programin Python we should never consider using a registered keyword or function name as a new variable. To solve the above program all we need to do is change the name ofstrvariable to something else which is not a reserved keyword and provide more meaning to the variab...
