Please answer the following question and write a program for python using Python IDLE

Transcribed Image Text:Warm-up
Write code using repetition to create the following patterns
999999999888888887777777666666555554444333221
Note; create means you must create with program code, not just assign it as a literal.
The problem
Write a program that asks the user for an integer between 1 and 25 and then generates the pattern that many
times.
Here are two sample runs:
how many rows? 5

Advice: there are two issues to deal with for this program - getting the number and printing out the pattern that
many times. A systematic approach is to
1. get your program working to print the pattern once, (a loop)
2. expand your program to print it multiple times, (nested loop_)
3. Expand to include the request for the number of times.

- [Python Language] [Python Language] Is it time for tea?Your friend lives in London England in a timezone that is normally 6 hours ahead of Toronto Canada. But sometimes London and Toronto switch to daylight savings time on different dates. If Toronto is on daylight savings time and London isn’t, then the time difference is only 5 hours. Conversely, if London is on daylight savings time and Toronto isn’t, the time change is 7 hours. Of course, if both are on daylight savings time, the difference is back to the standard 6 hours. Write a program that takes three lines of input: a float value representing the time in Toronto, whether Toronto is on daylight savings time (1 means yes, 0 means no), and whether London is on daylight savings time (1 means yes, 0 means no). It prints a float giving the time in London. One complication is that you should not print a time greater or equal to 24.0 or less than 0.0. Suggestion: At first don’t consider this complication, and test cases where the…arrow_forwardConcerning python The ___ statement allows the programmer access to functions not readily available in python directly. a. import b. module c. def d. randomarrow_forwardC++, must be at least 300 wordsarrow_forward
