Create a new folder in python and make it read only

igor_vitrenko [27]

Making the file read-only will not allow the file to be rewritten again. For this, we need to modify the permissions of the file. To achieve this, we will make use of the os module in Python more specifically, the chmod() of the os module.

The coding part is extremely simple and will contain very few lines as we are not doing much but changing the permissions. Using the chmod(), we can change the mode of the path, setting it to any mode using the suitable flags from the stat module. Both these modules come inbuilt with Python and hence you need not install anything additionally.

The entire code to change the file to read-only is as follows;

import os
from stat import S_IREAD
# Replace the first parameter with your file name
os.chmod("sample.txt", S_IREAD)
.

You can verify if the code was executed correctly by checking the file’s permissions. To do that :

Right-click on the file and click properties.
Under the attributes section, you will find the read-only checkbox checked.
I hope you found this article useful and it helped you make a file read-only. You can do more than just making the file read-only by using the appropriate flag from the stat module.

Explanation:

Summary:

The data set include two dependent variables which states High School annual earnings and BS annual earnings in the same small firm. Firstly, I used density plot function to view the distribution of two sets of variables. Secondly, I tested the skewness and kurtosis.Skewness of High School is -0.24041 which is left tail. Skewness of BS is 0.53476 which is right tail.Kurtosis of High School is 2.5695 which lower than 3 is platykurtic. Kurtosis of BS is 3.6449 which larger than 3 is leptokurtic. Thirdly, the sample population is 39 for each and has unknow standard deviation, so that I’m going to use t-test to perform the comparing analysis. The result shows p-value which equal to 0.866 is larger than significant value(alpha = 0.05). To the concludsion, there is no difference between yearly earnings of High School and of BS at a small firm.
