Trying to insert multiple checkbox values in separate rows in MySQL table in PHP not working [duplicate]

I have a simple form in PHP like below:

  <div class="col-md-4 ip"><label>Select Class</label><br>
            <?php
$ret=mysqli_query($con,"select * from class");
$cnt=1;
while ($row=mysqli_fetch_array($ret)) {

?>

<div class="form-check">
  <input name="classname[]" class="form-check-input" type="checkbox" value="<?php echo $row['class_name'];?>" id="flexCheckDefault">
  <label class="form-check-label" for="flexCheckDefault">
    <?php echo $row['class_name'];?>
  </label>
</div>

    <?php }?>
        </div>

Now I want the user selected checkboxes to get inserted in database in separate rows, so I did the following PHP code:

$classname=$_POST['classname'];

foreach ($classname as $pop ){
$ins_query="insert into study_material (`classname`) values ('$pop')";
}

Now here the issue is only the last selected checkbox value is getting inserted and others are not.

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
