<div>Thanks. </div>

<div>I am not aware if Python provides the feature of accessing the value by its bit poition:</div>
<div>Can we do "if read_data[bit_pos] === poll_val:" in Python? Can you please let me know little bit more about this line?</div>
<div>Whether Read_data will be declread as list() or dict()?</div>
<div>Thanks,</div>

<div class="Wj3C7c">Hello all,<br><br>I want to a write a method in Python to poll a register for '1' or '0'. It is kind of very simple in verilog, but not sure if python provides flexibility or not.<br><br>
My algorithm (kind of Verilog syntax where I can access the bits without any extra processing) is as follows:<br><br>poll_reg ( input bit_pos, input poll_val, reg_offset)<br>{<br>// In this bit_pos is the position of bit in my register read which are being polled to become poll_val. Poll_val can be either 0 or 1.<br>
<br> matched = 0;<br> while (matched != 1)<br> begin<br> read_data = read_reg(reg_offset);<br> if (read_data[bit_pos] == poll_val)<br> begin<br> matched = 1;<br>
end<br> else<br> begin<br> matched = 0;<br> end<br> end<br>}<br><br>Is there a way to do above in Python?<br>Thanks,<br>
