function to print text inverted (by a for loop)
I want to make a function that returns the text inverted. The problem here is, 'x' doesn´t store the inverted text I don´t know why.
THIS IS THE CODE
def text_inverted(w): for i in range(len(w)-1,-1,-1): x="" x+=w[i] return x print(text_inverted("hello"))
x outside of the for loop, because currently you are resetting x each time the for loops iterates:
def text_inverted(w): x = "" for i in range(len(w)-1,-1,-1): x+=w[i] return x print(text_inverted("hello")) #prints olleh
Another way of solving this is using Python's slicing notion:
def text_inverted(w): return w[::-1] print(text_inverted("hello"))
Python Reverse String - 5 Ways and the Best One, Here in this video tutorial we will learn how to reverse a string using for loop and function in Duration: 8:22 Posted: Feb 8, 2018 Next, the inner loop or nested for loop to handle the number of columns. Inner loop iteration depends on the values of the outer loop. Print start, number, asterisk, Pyramid, and diamond pattern using the print() function. Add a new line after each row, i.e. after each iteration of outer for loop so you can display pattern appropriately. Print Number pattern in Python. I have created multiple programs that print different styles of number patterns. Let see them one by one.
There is easier way.
Python Tutorial - Reverse a String Using for loop, Output: The original string is : Geeksforgeeks The reversed string(using loops) is : skeegrofskeeG. Explanation : In above code, we call a function to reverse a The GIF below shows a simple loop that goes through the integers 0 to 101 with a print(i) command and short lag time between each iteration. print everything after loop is finished The output to
The problem is that you reassign
x to be the empty string in each iteration of the
for loop. Move the statement
x = '' above the loop and your function should work fine.
>>> def text_inverted(w): ... x = '' ... for i in range(len(w)-1,-1,-1): ... x += w[i] ... return x ... >>> >>> print(text_inverted("hello")) olleh
By the way, the idiomatic way to reverse a string uses slice notation.
>>> 'hello'[::-1] 'olleh'
Reverse string in Python (5 different ways), Justify the given Text based on the given width of each line · Java program to print Even length words in a String · Shortest One of the solutions is given in Reverse words in a string . Repeat this until the loop is over and when the loop ends, print the string, the %s will make the printing of function wordReverse( $str ). When an user types in a sentence 'A short sentence', the function should do something with it and it should be printed on the same line. Let's say that function adds 't' to the end of each word, so the output should be. At shortt sentencet. However, at the moment the output is: How can I print the result on the same line easily? Or should I
The problem is that you are resetting the value of
x altogether in every iteration of the loop.
def inverted(w): i = 0; x = ''; length = len(w); while i < length: x += w[length - 1]; length = length - 1; return x; print(inverted('hello'));
Print words of a string in reverse order, There is no built-in method to reverse a string. However, strings The slice statement means start at string length, end at position 0, move with the step -1 (or one step backward). 5. 1 print (slicedString) # print the reversed string. 5. . RUN If statement 2 returns true, the loop will start over again, if it returns false, the loop will end. If you omit statement 2, you must provide a break inside the loop. Otherwise the loop will never end. This will crash your browser. Read about breaks in a later chapter of this tutorial.
As mentioned in other answers, you're not suppose to set the variable
x inside the for-loop; just initialize outside of it.
A better and simple alternative is use the Python build-in solution:
It will return the inverted
How do you reverse a string in Python?, def reverse (text): r = "" for i in range(len(text)): r+= text[len(text)-i-1] return r Try putting a print statement in the for loop to see the process. Now in a different situation where the last line of the function was "print a" assuming you removed the Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information.

My Code for this "reverse"-simple and direct, Remove print statement from function definition (just before while loop). def reverse(text): # Our empty string for the reversed text reversed_text = "" # Note: Serial.print() Description. Prints data to the serial port as human-readable ASCII text. This command can take many forms. Numbers are printed using an ASCII character for each digit. Floats are similarly printed as ASCII digits, defaulting to two decimal places.
7/15 Reverse: Practice Makes Perfect - Python, Printing file in reverse order Example 3: Write a program to create a text file. /*If so then loop ends using break */ 15 fputc(letter, fp); /*Value in letter output to file function to print the content of the file in the reverse order directly from the file, String Reversal. If you really want to reverse a string in the common sense, it is WAY more complicated. For example, take the following string ( brown finger pointing left, yellow finger pointing up ). Those are two graphemes, but 3 unicode code points. The additional one is a skin modifier.
RUDIMENTS OF COMPUTER SCIENCE: PART 2, There is no built-in function to reverse a String in Python. Example. Reverse the string "Hello World": txt = "Hello World"[::-1] print(txt) In this particular example, the slice statement [::-1] means start at the end of the string and end at position 0, move with mytxt = my_function("I wonder how this text looks like backwards")
