What is the printout of the call nPrint("a", 4)?

satela [25.4K]

Answer:

aaaa

Explanation:

We have a function nPrint which return type is void, it means it returns nothing.

we declare the two parameters, one parameter is string type and the second parameter is an integer type.

Then, it has a while loop that executes the statement again and again until the condition not FALSE.

Let dry run the code:

First, call the function nPrint("a", 4) bypassing the value in the argument.

then, the value receives by the parameters, the message contains "a" and n contain 4. After that, while loop checks the condition 4 > 0, which is TRUE and the program starts executing the statement.

The program prints the message on the screen "a" and then decreases the value of n by 1. So, the value of n becomes 3.

The above process repeats for the value of n = 3, 2, 1

and print the message "aaaa".

then, the condition becomes false and the program terminates the loop.

Therefore, the answer is aaaa

Write a program that prompts the user to enter a series of numbers between 0 and 10 asintegers. The user will enter all numbers

Anna71 [15]

Answer:

The program in Python is as follows:

import collections

from collections import Counter

from itertools import groupby

import statistics

str_input = input("Enter a series of numbers separated by space: ")

num_input = str_input.split(" ")

numList = []

for num in num_input:

if(num.lstrip('-').isdigit()):

if num[0] == "-" or int(num)>10:

print(num," is out of bound - rejecting")

else:

print(num," is valid - accepting")

numList.append(int(num))

else:

print(num," is not a number")

print("Largest number: ",max(numList))

print("Smallest number: ",min(numList))

print("Range: ",(max(numList) - min(numList)))

print("Mode: ",end = " ")

freqs = groupby(Counter(numList).most_common(), lambda x:x[1])

print([val for val,count in next(freqs)[1]])

count_freq = {}

count_freq = collections.Counter(numList)

for item in count_freq:

print(item, end = " ")

lent= int(count_freq[item])

for i in range(lent):

print("#",end=" ")

print()

Explanation:

See attachment for program source file where comments are used as explanation. (Lines that begin with # are comments)

The frequency polygon is printed using #'s to represent the frequency of each list element

Can someone tell me how this is a SyntaxError! (Python3)

Basile [38]

Answer:

The expression on line 9 required 2 brackets

Explanation:

Given

The attached code

Required

Why syntax error.

The error points to line 10, but the error is actually from line 9

To get an integer input, the syntax is:

variable-name = int(input("Prompt"))

From the attached code, the line 9 is:

amount = int(input("Enter cheese order weight: ")

By comparing the syntax to the actual code on line 9, only 1 of the brackets is closed.

<em>This, in Python 3 is a sytax error</em>
