Python Coding Work
- Write the definitionof a function twice, that receives an int parameter and returns an int that is twice the value of the parameter.
- Write the definition of a function square which recieves a parameter containing an integer value and returns the square of the value of the parameter.
- Write the definitionof a function typing_speed, that receives two parameters. The first is the number of words that a person has typed (an int greater than or equal to zero) in a particular time interval. The second is the length of the time interval in seconds (an int greater than zero). The function returns the typing speed of that person in words per minute (a float).
- Write a functionmin that has three str parameters and returns the smallest. (Smallest in the sense of coming first alphabetically, not in the sense of “shortest”.)
- Assume the availability of a function is_prime. Assume a variablen has been associated with positive integer. Write the statements needed to compute the sum of the first n prime numbers. The sum should be associated with the variable
Note: is_prime takes an integer as a parameter and returns True if and only if that integer is prime.
- Assume the availability of a function is_prime. Assume a variablen has been associated with positive integer. Write the statements needed to find out how many prime numbers (starting with 2 and going in increasing order with successively higher primes [2,3,5,7,11,13,…]) can be added before exceeding n. Associate this number with the variable
- Write the definition of a function oneLess which recieves a parameter containing an integer value and returns an integer whose value is one less than the value of the parameter.
- [Functions >> functions and if statements] Write the definition of a function powerTo which recieves two parameters, a double and an integer. If the second parameter is positive, the function returns the value of the first parameter raised to the power of the second. Otherwise, the function returns 0.
- Write the definition of a function absoluteValue that recieves a parameter containing an integer value and returns the absolute value of that parameter.
- Define a function called isPositive that takes a parameter containing an integer value and returns True if the paramter is positive or False if the parameter is negative or 0.
- Define a function called isSenior that takes a parameter containing an integer value and returns True if the parameter is greater than or equal to 65, and Falseotherwise.
Assume that max2 is a function that expects two int parameters and returns the value of the larger one.
Also assume that four variables, population1, population2, population3, and population4 have already been defined and associated with int values.
Write an expression (not a statement!) whose value is the largest of population1, population2, population3, and population4 by calling max2.
- Given a file object named output, associate it with a file named yearsummary.txt by opening the file for appending
- Given that corpdata is a file object used for reading data and that there is no more data to be read, write the necessary code to complete your use of this object.
- Using the file object input, write code that read an integer from a file called rawdata into a variabledatum (make sure you assign an integer value to datum). Open the file at the beginning of your code, and close it at the end.
- A file named numbers.txt contains an unknown number of lines, each consisting of a single positive integer. Write some code that reads through the file and stores the largest number read in a variablenamed maxvalue.
- A file named data.txt contains an unknown number of lines, each consisting of a single integer. Write some code that creates two files, dataplus.txt and dataminus.txt, and copies all the lines of data1.txt that have positive integers to dataplus.txt, and all the lines of data1.txt that have negative integers to dataminus.txt. Zeros are not copied anywhere.
- Two files named numbers1.txt and numbers2.txt both have an unknown
