For instance, range(a, b) functionality 144 bankruptcy five Loops >>> for v in range(4, 8): ... print(v) ... four five 6 7 >>> range(a) functionality range(a, b, okay) functionality step price the variety functionality has extra models. it's also possible to use range(a) or range(a, b, k). range(a) is equal to range(0, a). okay is used as step worth in range(a, b, k). the 1st quantity within the series is a. each one successive quantity within the series increases via the step worth okay. b is the restrict. The final quantity within the series needs to be under b. for instance, >>> for v in range(3, nine, 2): ... print(v) ... three five 7 >>> The step price in diversity (3, nine, 2) is two, and the restrict is nine. So, the series is three, five, and seven. The range(a, b, okay) functionality can count number backward if ok is unfavourable. thus, the series remains to be a, a + ok, a + 2k, and so forth for a detrimental okay. The final quantity within the series has to be more than b. for instance, count number backward >>> for v in range(5, 1, -1): ... print(v) ... five four three 2 >>> notice The numbers within the diversity functionality needs to be integers. for instance, range(1. five, eight. 5), range(8. 5), or range(1. five, eight. five, 1) will be unsuitable. ✓ fee element five. 6 consider the enter is two three four five zero (one quantity in keeping with line). what's the output of the next code? quantity = zero sum = zero for count number in range(5): quantity = eval(input("Enter an integer: ")) sum += quantity print("sum is", sum) print("count is", count number) five. 7 are you able to convert any for loop to your time loop? checklist the benefits of utilizing for loops. five. four Nested Loops a hundred forty five five. eight Convert the next for loop assertion to your time loop: sum = zero for i in range(1001): sum = sum + i five. nine are you able to constantly convert any whereas loop right into a for loop? Convert the next whereas loop right into a for loop. i = 1 sum = zero whereas sum < ten thousand: sum = sum + i i += 1 five. 10 count number the variety of iterations within the following loops: for count number in range(n): print(count) count number = zero whereas count number < n: count number += 1 (a) (b) count number = five whereas count number < n: count number = count number + three count number = five whereas count number < n: count number += 1 (c) (d) five. four Nested Loops A loop will be nested within one other loop. Nested loops include an outer loop and a number of internal loops. whenever the outer loop is repeated, the internal loops are reentered and commenced anew. directory five. 6 offers a software that makes use of nested for loops to exhibit a multiplication desk. Key element nested loops directory five. 6 MultiplicationTable. py 1 2 three four five 6 7 eight nine 10 eleven 12 thirteen 14 15 print(" Multiplication Table") # demonstrate the quantity identify print(" |", finish = '') for j in range(1, 10): print(" ", j, finish = '') print() # bounce to the hot line print("——————————————————————————————————————————") # show desk physique for i in range(1, 10): print(i, "|", finish = '') for j in range(1, 10): # show the product and align correctly print(format(i * j, "4d"), finish = '') print() # bounce to the hot line desk name desk physique nested loop reveal a line 146 bankruptcy five Loops Multiplication desk 1 2 three four five 6 7 eight nine ————————————————————————————————————————— 1 | 1 2 three four five 6 7 eight nine 2 | 2 four 6 eight 10 12 14 sixteen 18 three | three 6 nine 12 15 18 21 24 27 four | four eight 12 sixteen 20 24 28 32 36 five | five 10 15 20 25 30 35 forty forty five 6 | 6 12 18 24 30 36 forty two forty eight fifty four 7 | 7 14 21 28 35 forty two forty nine fifty six sixty three eight | eight sixteen 24 32 forty forty eight fifty six sixty four seventy two nine | nine 18 27 36 forty five fifty four sixty three seventy two eighty one this system monitors a identify (line 1) at the first line within the output.
