Python Lab 2a: Input and output
1. Ask the user to enter their name. Then say hello and repeat their name.
2. Ask the user to enter their age. Print out their age 5 years from now.
3. Use concatenation and str() to print a message telling the user how old they will be in 5 years.
4. Ask the user to enter in values that might be floating point.
5. Print out the result of the calculation in a single print statement, using concatenation.
6. If Time
In Python, the input() function is used to accept input. The result is stored as a string type.
name = input ('what is your name?')
print ('Hello ' + name)
To be able to add 5 to the user input, it has to be converted to an integer.
x = int(input ('what is your age?')
print (x + 5)
When you are printing out a string message and want to concatenate a number onto the string, use str() to convert a numeric value to a
string.
If the user entered 27, your output should be similar to the following:
In 5 years you will be 32 years old
Let's calculate the amount of pay an hourly worker will get for working in a week. Ask the user to enter in the number of hours worked,
convert this to a floating point value, and store this in a variable.
Enter the number of hours worked: 33.7
Ask the user to enter in their hourly wage, but not with the $, convert this to a floating point value, and store the result in a variable.
Enter your hourly wage, without the $: 11.32
Calculate their weekly paycheck and print out a message, using one print statement, and using concatenation.
Your gross pay this week is $ 381.484
If you have time, search on the web for a way to round to 2 decimal places. Change your output to show just 2 places after the decimal.
