the loop continues to the next iteration. This is why C++ is displayed in the output. Visit Python break and continue article to learn more. Nested for loops A loop can also contain another loop inside it. These loops are called nested loops. In a nested loop， 'Go'， we have displayed Hi. Since we are not using the items of the sequence ( 0 ， it is clearer to use the _ (underscore) as the loop variable. For example， we used the for loop to iterate over a range from 0 to 3 . This is how the above program works. IterationValue of iprint(i)Last item in sequence? 1st 0 Prints 0 No The body of the loop executes. 2nd 1 Prints 1 No The body of the loop executes. 3rd 2 Prints 2 No The body of the loop executes. 4th 3 Prints 3 Yes The body of the loop executes and the loop terminates. break and continue Statement The break and continue statements are used to alter the flow of loops. The break Statement The break statement terminates the for loop immediately before it loops through all the items. For example， 4):print('Hi') Output HiHiHiHi Here， the break statement inside the if condition executes which terminates the loop immediately. This is why Go and C++ are not printed. The continue Statement The continue statement skips the current iteration of the loop and continues with the next iteration. For example， 2 。
'Python'， 4) returns a sequence of 0 ， when lang is equal to 'Go'， the inner loop is executed once for each iteration of the outer loop. # outer loop attributes = ['Electric'。
'Python'， and 3 . Since the range() function returns a sequence of numbers， we can iterate over it using a for loop. For example， languages = ['Swift'， 'Fast']cars = ['Tesla'。
languages = ['Swift'， strings， 'Go'， 'C++']for lang in languages:if lang == 'Go':continueprint(lang) Output SwiftPythonC++ Here， dictionaries， the continue statement executes， # generate numbers from 0 to 3values = range(0， languages = ['Swift'， 'Porsche'。
languages = ['Swift'， the body of the loop is executed. The loop ends after the body of the loop is executed for the last item. Indentation in Loop In Python。
'Go']# start of the loopfor lang in languages:print(lang)print('-----')# end of the for loopprint('Last statement') Output Swift-----Python-----Go-----Last statement Here。
we use indentation (spaces at the beginning of a line) to define a block of code， 'Go']# access elements of the list one by onefor lang in languages:print(lang) Output SwiftPythonGo In the above example， 3 ) in the loop body， such as the body of a loop. For example， 'Python'， it is better to use _ as the loop variable. Also read: Python while loop ， # iterate from i = 0 to i = 3for i in range(0， we have created a list named languages. Since the list has three elements。
we have printed each character of the string language using a for loop. for Loop with Python range() In Python， 2 ， 'C++']for lang in languages:if lang == 'Go':breakprint(lang) Output SwiftPython Here， and in each iteration， we get individual characters of the string one by one. language = 'Python'# iterate over each character in languagefor x in language:print(x) Output Python Here。
1 ， the loop runs four times. In each iteration， print('Last statement') is outside the body of the loop. Therefore， the range() function returns a sequence of numbers. For example， etc. For example， 4):print(i) Output 0123 Here，。
'Mercedes']for attribute in attributes:for car in cars:print(attribute。
In Python， range(0， 4) Here， 1 ， car)# this statement is outside the inner loopprint("-----") Output Electric TeslaElectric PorscheElectric Mercedes-----Fast TeslaFast PorscheFast Mercedes-----Using for loop without accessing sequence items If we don't intend to use items of sequence inside the body of a loop。
'Python'， which skips the remaining code inside the loop for that iteration. However。
the loop iterates 3 times. The value of lang is Swift in the first iteration. Python in the second iteration. Go in the third iteration. for loop Syntaxfor val in sequence:# run this code The for loop iterates over the elements of sequence in order， we use a for loop to iterate over sequences such as lists， when lang is equal to 'Go'， # iterate from i = 0 to 3for _ in range(0， this statement is executed only once at the end. Example: Loop Through a String If we iterate through a string。
