Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, and then closes the file.
Body Mass Index
Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:
BMI = weight × 703 / height2
where weight is measured in pounds and height is measured in inches.
The file is in the format
name weightInKG heightInCM
You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch).
The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight.
Your output should look like
A person’s weight…
File Iteration: Introduction
A text file is essentially a sequence of lines. Here is a typical coding pattern for processing each line of a file in turn:
Open the file for reading.
Use a for loop to iterate over the lines of text, executing a block of one or more statements to process each line.
Close the file.
Finish processing (print, return, etc.) if needed
NOTE: You will need to use this pattern, or some variation of it, to solve the remaining coding problems in this assignment.
As the following for loop iterates through each line of the file, the loop variable (`line`) represents the current line of the file as a string of characters.
myFile = open("someTextFile.txt", "r") for line in myFile: do something on each iteration do a second thing on each iteration etc... myFile.close()
PROBLEM: Read a string from standard input using python. Then, iterate over a text file called "cards.txt" and, for each line of the file that starts with the string read from standard input,…

Add a variety of records to the file. A sample file looks like: Write a program that opens the file and reads the records one by one. The program will skip any records where the gender preference is not a match. Of those records that match the gender preference, check to see if the age and height are between the maximum and minum preferences. Then check to see if the smoking preference and eye color are also a match. If at least 3 of the remaining fields match, consider the record a partial match, and print it in the report. If all 4 of the remaining fields match, the record is a perfect match and print it in the report with an asterisk next to it. At the end of the program, close the file and report how many total records there were of the specified gender, how many were a partial match, and how many were a perfect match.

Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7.
