Building a String Library
Sometimes when programming you need to introduce a new data type and develop a library of functions for manipulating instances of that data type. Often this is done as methods on a new class but not always.
In this assignment, you'll be defining a collection of functions on strings, most of which already exist as methods on the str class. However, you should pretend that they don't already exist and define them as functions. Of course, you can't just use the existing methods. This will give you a bunch of practice on manipulating strings and also on defining functions.
In this assignment, you'll be defining a collection of functions on strings. You should define each of these as a new function with a function header as below. The description of each is in the comment supplied. Recall that strings are immutable, so you will have to return a new copy of the string for those that call for you to return a string. If you are returning the same string as the input, just return it; there is no need to make a new copy, and it wouldn't anyway.
The only string functions/methods to use:
ord, chr
indexing and slicing
append (i.e., ``+'')
len, in, not in
equality comparison (== or !=))
Looping over strings (while or for loops) and selection (if statements) are allowed. BUT You cannot convert the strings to other types such as lists.
Define each of the following functions, with semantics as indicated by the comment. In each of the following ch is a single character, str, str1, str2 are strings, and i is a non-negative integer. You do not have to validate the inputs, except as indicated; you can assume these types.
At least one question asks you to return two values. That really means returning a tuple (pair) of values. You do that as follows:
return value1, value2
This actually returns the pair (value1, value2). The caller can then assign the members of the pair to two variables:
x, y = pairReturningFunction() # assumes function returns a pair
z, w = (value1, value2) # assigning a tuple to 2 variables
If you like, you can use earlier functions in later ones, or define helper functions, though it shouldn't really be necessary. Note that some of these are trivial to write, while others are a bit harder. I have done the first one for you.
def myAppend( str, ch ):
# Return a new string that is like str but with
# character ch added at the end
return str + ch
def myCount( str, ch ):
# Return the number of times character ch appears
# in str.
def myExtend( str1, str2 ):
# Return a new string that contains the elements of
# str1 followed by the elements of str2, in the same
# order they appear in str2.
def myMin( str ):
# Return the character in str with the lowest ASCII code.
# If str is empty, print "Empty string: no min value"
# and return None.
def myInsert( str, i, ch ):
# Return a new string like str except that ch has been
# inserted at the ith position. I.e., the string is now
# one character longer than before. Print "Invalid index" if
# i is greater than the length of str and return None.
def myPop( str, i ):
# Return two results:
# 1. a new string that is like str but with the ith
# element removed;
# 2. the value that was removed.
# Print "Invalid index" if i is greater than or
# equal to len(str), and return str unchanged and None
def myFind( str, ch ):
# Return the index of the first (leftmost) occurrence of
# ch in str, if any. Return -1 if ch does not occur in str.
def myRFind( str, ch ):
# Return the index of the last (rightmost) occurrence of
# ch in str, if any. Return -1 if ch does not occur in str.
def myRemove( str, ch ):
# Return a new string with the first occurrence of ch
# removed. If there is none, return str.
def myRemoveAll( str, ch ):
# Return a new string with all occurrences of ch.
# removed. If there are none, return str.
def myReverse( str ):
# Return a new string like str but with the characters
# in the reverse order.
Expected output:
>>> from MyStringFunctions import *
>>> s1 = "abcd"
>>> s2 = "efgh"
>>> myAppend( s1, "e" )
'abcde'
>>> myCount( s1, "e")

Explanation:
The operating system is the type of software that is responsible for managing the processor time and also the memory allocation in the system. The operating system mainldeals with the processor time by scheduling the processor work done in the system.
The OS mainly controls the system and then schedule the execution of various types of function by the central processing unit (CPU). It also controls the memory allocation in the system.
The part of the computer responsible for managing memory allocation for all applications is the operating system. The correct option is B.
What is an operating system?The operating system is the kind of software in charge of controlling the system's memory allocation and CPU usage. By scheduling the system's processor work, the operating system primarily manages processor time.
The operating system (OS) primarily manages the system and schedules the central processor unit's performance of many types of functions. Additionally, it manages the system's memory allocation.
The CPU is the brain of the computer. It manages all the functions of the computer. It is a small rectangle chip-like structure present inside the box with other parts.

The NYC_Bicycle_Counts_2016_Corrected.csv gives information on bike traffic across a number of bridges in New York City. In this path, the analysis questions we would like you to answer are as follows: 1. You want to install sensors on the bridges to estimate overall traffic across all the bridges. But you only have enough budget to install sensors on three of the four bridges. Which bridges should you install the sensors on to get the best prediction of overall traffic
The ideal would be to install sensors on bridges at the main points of the city, to get a general idea about the traffic in the city.
We can arrive at this answer because:
The bridges that lead to the main points of the city tend to have more movement of people and vehicles.In this case, we can say that these bridges have more intense and constant traffic, which can promote a generalized view of traffic on other bridges.Therefore, by installing sensors to analyze traffic on these bridges, it would be possible to project the data collected from the sensors on less busy bridges, according to the context in which they apply.In this case, the bridges that lead to commercial centers, highways, tourist places, and other important points of the city, must receive the censors.
