('Please input the minutes :...'))Hours = minutes/60Mins = minutes-hours * 60Print "% I: % I" % (hours, mins) 6-10.String. Write a function to return a string similar to the input string, which requires case-sensitivity inversion. For example, if "Mr. Ed" is input, "mR. eD" should be returned as the output.[Answer]The Code is as follows:Input = raw_input ('Please input a string :...')Output =''For I in input:If I = I. upper ():Output = output + I. lower ()Else:Output = output + I. upper ()Print

Python source code analysis has many tips in the actual operation process. We will introduce you to this tip so that you can better apply it in the Python source code analysis process, the following are some tips for this article. Python source code analysis-Deep Exploration of Dynamic Language core technology is a high-level Chinese original book that explains t

of the class, easy to handle exceptions;Development experience:The exception is the main processing of reading files, but also can be used with the method of reading files; can also be used for network connections where exceptions can include a large number of error messages for error handling.Code:Class Shortinputexception (Exception): def __init__ (self, length, atleast): exception.__init__ (self) self.length = length self.atleast = atleast while True: try:

-coordinate. Copy the previous grid values, write the code to print out the image ... Oo. Oo... Ooooooo. Ooooooo ... Ooooo ..... Ooo....... O.... Tip: You need to use loop nesting loops, print out grid[0][0], then grid[1][0], then grid[2][0], and so on, until Grid[8][0]. This completes the first line, so the next line is printed. The program will then print out grid[0][1], then grid[1][1], then grid[2][1], and so on. The program finally prints out grid[8][5]. Also, if you do not want to autom

the numbers are printed out. The range (10) call produces a scope from 0 until (but not including) 10,range (0,10) explicitly tells the loop to start at 0, range (0,10,1)Explicitly tells the loop each iteration variable plus 1.13, write a small program, using for loop, print out from 1 to 10 numbers. Then, using the while loop, write an equivalent program to print a number from 1 to 10.# Write a short program that uses a for loop to print out numbers from 1 to 10. for in range (1,11): prin

sometimes referred to as "The simplest, impossible mathematical problem". Remember to convert the return value of input () to an integer using the INT function, or it will be a string. Tip: If number% 2 = = 0, integer number is even. If number% 2 = = 1, it is odd.

Afternoon brain Watt, thought for a while did not come up with algorithms, just convulsions finally realized, hereby recorded. ￣-￣| |Topic(a) Create a function with the name FINDCHR (), FINDCHR () to find the character char in string strings, find the index that returns the value, otherwise return-1.(b) Create another function called RFINDCHR (), looking for the character char last occurrence. It works like FINDCHR (), but it looks forward from the end of the string.(c) Create a third function,

The problem with Python exercises is as follows:Summary: The bonus paid by the enterprise is based on the profit commission. Profit (I) less than or equal to $100,000, the bonus can be raised by 10%, the profit is higher than $100,000, less than $200,000, the portion of less than 100,000 yuan by 10% commission, higher than the portion of 100,000 yuan, a commission of 7.5%, 200,000 to 400,000, higher than 200,000 yuan, can commission 5% , between 400,0
