Varvara68 [4.7K]

The undo function is used to reverse a mistake, such as deleting the wrong word in a sentence. The redo function restores any actions that were previously undone using an undo. ... For example, if you typed a word, and then deleted it using an undo, the redo function would restore the word you delete

What do you mean by redo?

: to do (something) again especially in order to do it better. : to change (something, such as a room or part of a room) so that it looks new or different. See the full definition for redo in the English Language Learners Dictionary.

<em>What is Undo ?</em>

<em>What is Undo ?Undo is an interaction technique which is implemented in many computer programs. It erases the last change done to the document, reverting it to an older state.

What is the first thing you should do to find a mean and range of data?
KatRina [158]

Answer

To find mean of data add all the numbers in the set of data and divide the sum by the number of addends.

To find range, identify the difference between the highest value and lowest value in the set of data.

Explanation

Mean, mode, median and range are the primary measurements used to get the measures of central tendencies. To get the mean and range; first arrange the data in an ascending order, then identify the highest value and the lowest value in the set. The difference between these two data values gives the range of the set of values. For the mean, add all the set of values and then divide their sum with the number of values in the set of data.

The readline method reads text until an end of line symbol is encountered, how is an end of line character represented
zhannawk [14.2K]

Answer:

\n

Explanation:

readline() method is used to read one line from a file. It returns that line from the file.    

This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.

So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.

For example if the file "abc.txt" contains the lines:

Welcome to abc file.

This file is for demonstrating how read line works.

Consider the following code:

f = open("abc.txt", "r")  #opens the file in read mode

print(f.readline()) # read one line from file and displays it

The output is:

Welcome to abc file.    

The readline() method reads one line and the print method displays that line.
