Removing index column in pandas when reading a csv

I have the following code which imports a CSV file. There are 3 columns and I want to set the first two of them to variables. When I set the second column to the variable "efficiency" the index column is also tacked on. How can I get rid of the index column?

df = pd.DataFrame.from_csv("Efficiency_Data.csv", header=0, parse_dates=False)
energy = df.index
efficiency = df.Efficiency
print efficiency

I tried using

del df["index"]

after I set

energy = df.index

which I found in another post but that results in "KeyError: "index" "

How can I make a time delay in Python?

I would like to know how to put a time delay in a Python script.

Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

Answer #1

os.remove() removes a file.
os.rmdir() removes an empty directory.
shutil.rmtree() deletes a directory and all its contents.

Path objects from the Python 3.4+ pathlib module also expose these instance methods:

pathlib.Path.unlink() removes a file or symbolic link.
pathlib.Path.rmdir() removes an empty directory.

imp Python module is always a bit confusing 😭 Removing index column in pandas when reading a csv is not the only problem I encountered. I just hope that will not emerge anymore

I was preparing for my coding interview, thanks for clarifying this - Removing index column in pandas when reading a csv in Python is not the simplest one. Will use it in my bachelor thesis
