import socket
addr = ("", 8080) # all interfaces, port 8080
if socket.has_dualstack_ipv6():
s = socket.create_server(addr, family=socket.AF_INET6, dualstack_ipv6=True)
else:
s = socket.create_server(addr)
Here is what the above code is Doing:
1. Create a socket object.
2. Bind the socket to the address.
3. Listen for connections made to the socket.
4. Accept connections.
5. Close the connection.
import matplotlib.pyplot as plt import seaborn as sns figure = plt.figure(figsize=(12, 6)) sns.heatmap(train_data.corr(), annot=True,cmap=plt.cm.cool) plt.tight_layout() plt.xlabel(‘Corr’) plt.show() Here is what the above code is Doing: 1. We are creating a figure object with the size of 12×6 inches. 2. We are using the seaborn heatmap function to plot the correlation matrix. 3. We are using…
In [30]: df = pd.DataFrame({‘subscriber_id’:[1,2,3,4,5]}) ”’ subscriber_id 0 1 1 2 2 3 3 4 4 5 ”’ mask = df[‘subscriber_id’].isin([2,4,5]) ”’ 0 False 1 True 2 False 3 True 4 True ”’ df.loc[mask] ”’ subscriber_id 1 2 3 4 4 5 ”’ Here is what the above code is Doing: 1. Create a DataFrame…
col = df.pop(“Mid”) df.insert(0, col.name, col) Here is what the above code is Doing: 1. We’re using the pop() method to remove the column named “Mid” from the df dataframe. 2. We’re using the insert() method to insert the column back into the df dataframe at the 0th index. 3. We’re using the name attribute…
n % k == 0 Here is what the above code is Doing: 1. We’re defining a function called is_divisible_by_k that takes two arguments, n and k. 2. We’re checking if n is divisible by k. 3. If n is divisible by k, we return True. 4. If n is not divisible by k, we…
from fractions import Fraction float(sum(Fraction(s) for s in ‘1 2/3′.split())) Here is what the above code is Doing: 1. The sum() function takes an iterable and returns the sum of its elements. 2. The generator expression (s for s in ‘1 2/3’.split()) returns a generator that yields the strings ‘1’, ‘2/3’, and ” (the empty…
if variable > 10 print(variable + str(” > 10″)) # there is no “:” next to the 10 in the 1st line, that will activate an error which is “SyntaxError : invalid syntax” # [pyflakes] significate something is missing in your code Here is what the above code is Doing: 1. It’s checking if the…
