Whenever I try to use a search cursor from arcpy in pycharm, I get this unresolved reference error. I should note that it was working fine earlier in the night, I have no idea what happened.     I've tried everything in this Q&amp;A already:     Other arcpy functions seem to work fine. I've also tried restarting computer and reinstalling pycharm. I can use the search cursor when I use IDLE.
How would I setup  to recognize import arcpy?   I'd like to use PyCharm to develop and debug geoprocessing tool.
A Linear Diophantine Equation is of the following form:                                                                                        $Ax+By+C=0$, where $x_1 \leq x \leq x_2$ and $y_1 \leq y \leq y_2$.  If the value of $A,B,C,x_1,x_2,y_1,y_2$ are given and $x_1 \leq x_2$ and $y_1 \leq y_2$, then how many solutions can be found? How can I find out the total number of solutions according to the above condition. I found the following blog title without a question mark from :     How to ease Afghanistan’s progress in cricket   Is it grammatical, if we don't put question mark in questions of titles? I think this blog title should have been like this:     How to ease Afghanistan’s progress in cricket?   I also found the following blog title from  without a question mark:     Election rigging 101: How to steal a mandate   However, I found a question mark from other blog title of :     Elections 101: What is the ECP and what does it do on election day? Are there well known HTTP-only sites? Captive WIFI portals suck.  So often when I open in a browser (Desktop Chrome or Mobile Chrome) a HTTP site, I get the captive portal, but with auto-completion and so quickly I connect again to WIFI.  The problem is that after the captive portal redirects, I'll have also a HTTPS redirect and Chrome remember the certificate and to use only HTTPS.  So I cannot use the same site twice (in a session).  A well-known public HTTP only site will resolve this.  Well-known sites usually work, causing some less debugging of the WIFI connection. Is the function $f(x)=|x|^{1/2}$ Lipschitz continuous? Is the function $f(x)=|x|^{1/2}$ Lipschitz continuous near $0$? If yes, find a constant for some interval containing $0$.   I think the answer is yes since I can find $L=1$ that satisfies Lipschitz continuity criteria in a interval close to $0$, am I right? What happens when a moderator clicks 'leave open' in the close-vote queue? It takes  clicking "leave open" in the close-vote queue to remove the question from the queue.  How about diamond mods?  Do they remove it from the queue in one click, or not? We are provided with a string A (may contain repeated characters as well ). One needs to make all possible permutations of A , and find out how many pairs of strings chosen from these permutations are not similar.  Two strings are similar if we can make both of them exactly same by carrying out at most 1 swap in each of them .  Example :- if we are provided with string abcd  , then for permutation abcd , the permutations which are not similar to it are bcda , bdac , cadb , cdba , dabc , dcab . Similar is the case for other permuations as well. So overall number of desired pairs are 24*6=144 .  I tried solving it for each possible pair by approach mentioned here     But as the permutations can be large enough , I need a better approach of solving this. Is there a list of error codes for Minecraft? What do potential postdoc advisers seek in research statement letters? I am putting together my application for a postdoctoral position in theoretical condensed matter physics. The position is not a fellowship and is a regular postdoc position. If you have gone through the process of applying for such positions a number of times, or, even better, if you have reviewed such research statement letters, what are the main points that are sought/you seek in such letters? Specifically, should I put more emphasize on my PhD research to demonstrate my "depth of knowledge" on projects I have worked on (past research), or dwell more on things that I want/am capable to do (future research)? Running Commands on Remote Linux Server Using SSH I am writing a Bash Script wherein I need to run some set of commands on a remote Linux server from my local computer using SSH. I want the results to be displayed on the terminal screen or dump the results in a file on my local system.   How can achieve this? Is the following syntax correct?  \#!/bin/bash . . . .  ssh &lt;user&gt;@&lt;remote_host&gt; 'COMMAND &gt;&gt; /path/to/file ; scp /path/to/file &lt;user&gt;@&lt;local_host&gt;:&lt;location&gt;; exit' . .   Thanks in advance. Use worksheet name as a variable in a lookup Updating a field programmatically, hook_node_update Algorithm to find the irreducible polynomial What algorithm can be used find an irreducible polynomial of degree $n$ over the field $GF(p)$ for prime $p$. The reason I ask is I want to make a program for finite field arithmetic, but creating a field $GF(p^k)$ requires finding a irreducible polynomial. (I'm mostly interested in $GF(2^k)$.) How do I prove that $x^p-x+a$ is irreducible in a field with $p$ elements when $a\neq 0$? Let $p$ be a prime. How do I prove that $x^p-x+a$ is irreducible in a field with $p$ elements when $a\neq 0$?   Right now I'm able to prove that it has no roots and that it is separable, but I have not a clue as to how to prove it is irreducible. Any ideas? How can I forward delete on iOS? Is there a way to delete text in front of the caret using the iOS software keyboard? The small wireless hardware keyboard accomplishes this with a fn+delete, so there might be a way to use multiple keys to accomplish the same task in iOS? Solve $x^{5} \equiv 2$ mod $221\ $ [Taking modular $k$'th roots if unique] What is the correct way to pluralize an acronym / initialism? For example, if I wanted to write the equivalent of  There are many automated teller machines in this city.  Would it be  There are many ATMs in this city.  or  There are many ATM's in this city. (could get confused with possessive form or contraction).  or just  There are many ATM in this city. (assuming the final s is included in Machines represented by M).  Maybe something else? How can I view the time of a text message in iOS 7? If $f(xy)=f(x)f(y)$ then show that $f(x) = x^t$ for some t Let  $f(xy) =f(x)f(y)$ for all $x,y\geq 0$. Show that $f(x) = x^p$ for some $p$.    I am not very experienced with proof. If we let $g(x)=\log (f(x))$ then this is the same as  $g(xy) = g(x) + g(y)$   I looked up the hint and it says let $g(x) = \log f(a^x) $   The wikipedia page for functional equations only states the form of the solutions without proof.  Attempt  Using the hint (which was like pulling a rabbit out of the hat)  Restricting the codomain $f:(0,+\infty)\rightarrow (0,+\infty)$ so that we can define the real function $g(x) =  \log f(a^x)$ and we have $$g(x+y) = g(x)+ g(y)$$   i.e $g(x) = xg(1)$ as $g(x)$ is continuous (assuming $f$ is).  Letting $\log_a f(a) = p$ we get $f(a^x) =a^p $. I do not have a rigorous argument but I think I can conclude that $f(x) = x^p$ (please fill any holes or unspecified assumptions) Different solutions are invited Perhaps this is trivial: how does one prove that the work done by a homogeneous gravitational field on a system of particles is equal to the work done on a point mass with the total mass of the system, located at the center of mass of the system. How to find application's path from command line? For example, I have git installed on my system. But I don't remember where I installed it, so which command is fit to find this out?
