Create a new folder in python and make it read only

1 answer:

8 0

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.

Suppose you have a program P and 90 percent of P can be parallelized, but 10 percent of P is inherently sequential and cannot be

Answer:

Means no matter how many processors you use, speed up never increase from 10 times.

Explanation:

If a problem of size W has a serial component Ws,then performance using parallelism:

Using Amdahl's Law:

Tp = (W - Ws )/ N + Ws

Here, Ws = .1,

W - Ws = .9

Performance Tp = (.9 / N) + .1

---------------------------------------------------------

Speed Up = 1 / ( (.9 / N) + .1)

If N -> infinity, Speed Up <= 10

Means no matter how many processors you use, speed up never increase from 10 times.

}

}else{

System.out.println("firstName and lastName must contain letters only.");

}

for(int i=0;i<arr.length;i++){

if(name.equals(arr[i]))

return true;

}

return false;

}

public void setAvailableUserNames(String[] usedNames){

names = this.possibleNames.toArray(names);

}

public boolean isValidName(String str){

if(str.length()==0) return false;

for(int i=0;i<str.length();i++){

if(str.charAt(i)<'a'||str.charAt(i)>'z' && (str.charAt(i)<'A' || str.charAt(i)>'Z'))

return false;

}

return true;

}

public static void main(String[] args) {

UserName person1 = new UserName("john","smith");

System.out.println(person1.possibleNames);

String[] used = {"harta","hartm","harty"};

UserName person2 = new UserName("mary","hart");

System.out.println("possibleNames before removing: "+person2.possibleNames);

person2.setAvailableUserNames(used);
