+
+Q-2 addd a new user without using adduser & useradd cmd
+A- add a new user
+     #vim /etc/passwd
+     then press insert key and add user
+
+Q-3 can we change the umask value to 0888.
+A- No, we can't change the umask value to 0888.
+     highest value is 0777
+     -rwx have h 777 value
+
+Q-4 how to add a new user with a unique user id &check out the unique id of that user.
+A- #useradd jass
+    #usermod jass
+    #id jass
+    #sudo usermod -u 1345 jass
+
+Q-5 how to change the group of any folder.
+A- 1) 
+      In kali we can't change the root.
+      In other o.s. we chnage folder
+    2)
+      #chgrp jass file.txt
+        go to jass then #ll to see jass group is make or not.
+
+
+
+Assignment -3 
+Q-1 create & compress the file with bzip2
+A- #bzip2 jass
+    #bunzip2 jass
+
+Q-2 what should be the argument to be given to unzip that file .
+A- #gzip jass
+    #gunzip jass

+A- #cat < jass > file.txt
+
+Q-4 how to change the shell of user to "/bin/sh" at the time of adding the user.

+python class 1
+1)what is jpython and cpython?
+ans.-cypthon is both the compiler as well as the interpreter. it will convert the written python code into the byte code before interpreting it.
+it is the default and most widely used implementation of the language.
+jpython-it is the implementation of python working on the java platform.
+
+2) basic difference between pyhton2 and pyhton3.
+ans.- in python2 it takes the user input and default storing os string is in the ASCII code.whereas in python3 we take only input and default storing of string is in unicode.
+
+3)difference between ASCII Code and unicode.
+ans-
+Unicode and ASCII both are standards for encoding texts
+ASCII CODE-ASCII is a character-encoding scheme and it was the first character encoding standard.ASCII uses 7 bits to represent a character. It has 128 code points, 0 through 127.  It is a code for representing English characters as numbers, with each letter assigned a number from 0 to 127.
+ 
+UNICODE-Unicode is a universal international standard character encoding that is capable of representing most of the world's written languages. It assigns each character a unique number, or code point. 
+ 
+
+1) what will be the output of 3+4**6-9*10/2
+ans- exponent>multiplication=division>addition=subtraction
+=3+4**6-9*5
+=3+4096-45
+=4099-45=4054
+so by this  the answer will be 4054.
+
+2)lets say i have a string "hello this side regex". count the total no. of vowels present in the  string.
+ans-
+string=input("Enter string:")
+vowels=0
+for i in string:
+      if(i=='a' or i=='e' or i=='i' or i=='o' or i=='u' or i=='A' or i=='E' or i=='I' or i=='O' or i=='U'):
+      vowels=vowels+1
+print("Number of vowels are:",vowel)
+
+3)find out the area of the triangle . you have to take the value from the user about the base and the height.
