Answer:
def typeHistogram(it,n):
d = dict()
for i in it:
n -=1
if n>=0:
if str(type(i).__name__) not in d.keys():
d.setdefault(type(i).__name__,1)
else:
d[str(type(i).__name__)] += 1
else:
break
return list(d.items())
it = iter([1,2,'a','b','c',4,5])
print(typeHistogram(it,7))
Explanation:
- Create a typeHistogram function that has 2 parameters namely "it" and "n" where "it" is an iterator used to represent a sequence of values of different types while "n" is the total number of elements in the sequence.
- Initialize an empty dictionary and loop through the iterator "it".
- Check if n is greater than 0 and current string is not present in the dictionary, then set default type as 1 otherwise increment by 1.
- At the end return the list of items.
- Finally initialize the iterator and display the histogram by calling the typeHistogram.
Answer:
gpresult
Explanation:
Group Policy provides the system administrator with settings that would be necessary to manage the different user accounts available in an organization. It also controls their work environment centrally by configuring the user Operating System (OS), applications and user accounts.
Group policy settings or configurations are referred to as Group Policy Objects (GPOs). These objects can be linked to organizational units (OUs), domains or sites.
There are various group policy commands such as;
- rstrui (System Restore tool will run),
- runas (using different permission to run a tool or program),
- tasklist (currently running programs are shown
- gpupdate (Group policies are refreshed)
- gpresult (group policy configurations are displayed for verification)
gpresult command can be used to verify the group policy configurations for adjustment or optimization. The technician can start troubleshooting from viewing the active settings, then running the rstrui to start the System Restore utility to restore the computer to an earlier date
Answer:
understanding component interaction
Answer:
200 nm
Explanation:
We need a constructive interference to see the bright reflection
we know that 
where m=1 and 
is the wavelength of the gasoline
so 
putting the value of m and in thickness equation
so the thickness of the film will be 200 nm
The answer is user EXEC mode. This is for setting, viewing, and testing system processes. In common, the user EXEC commands let you to link to remote devices, modify terminal line settings on a temporary basis, perform basic tests, and list system information. This also used by common system administrators, while the privileged EXEC mode is used by the root administrator. Use the enable and disable instructions to shift between the two levels. Access to the user-level EXEC command line needs a valid password.
