寫一個(gè) Python 程序，使用 For 循環(huán)和 While 循環(huán)對(duì)列表執(zhí)行算術(shù)運(yùn)算，并給出一個(gè)實(shí)例。
對(duì)列表執(zhí)行算術(shù)運(yùn)算的 Python 程序示例
在這個(gè) python 程序中，我們使用 For 循環(huán)來迭代給定列表中的每個(gè)元素。在 Python 循環(huán)中，我們對(duì)第一個(gè)和第二個(gè)列表的元素執(zhí)行算術(shù)運(yùn)算。
# Python Program to Perform List Arithmetic Operations
NumList1 = [10, 20, 30]
NumList2 = [5, 2, 3]
add = []
sub = []
multi = []
div = []
mod = []
expo = []
for j in range(3):
add.append( NumList1[j] + NumList2[j])
sub.append( NumList1[j] - NumList2[j])
multi.append( NumList1[j] * NumList2[j])
div.append( NumList1[j] / NumList2[j])
mod.append( NumList1[j] % NumList2[j])
expo.append( NumList1[j] ** NumList2[j])
print("\nThe List Items after Addition = ", add)
print("The List Items after Subtraction = ", sub)
print("The List Items after Multiplication = ", multi)
print("The List Items after Division = ", div)
print("The List Items after Modulus = ", mod)
print("The List Items after Exponent = ", expo)在這個(gè)對(duì)列表執(zhí)行算術(shù)運(yùn)算的 Python 程序示例中，NumList1 = [10，20，30]，NumList2 = [5，2，3]。為此，我們使用 Python 算術(shù)運(yùn)算符
對(duì)于循環(huán)–第一次迭代:對(duì)于范圍(3)中的 0–條件為真 add . append(numlist 1[0]+numlist 2[0])=>add . append(10+5) add[0]= 15 append(10–5)=>sub[0]= 5 multi . append(10 * 5)=>multi[0]= 50 div . append(10/5)=>div[0
第二次迭代:對(duì)于范圍(3)中的 1–條件為真 追加(20 + 2) = >追加[1] = 22 追加(20–2)=>子[1] = 18 多追加(20 * 2) = >多[1] = 40 div 追加(20 / 2) = > div[1] = 10 mod 追加(20 % 2) = > sub[1] =
第三次迭代:對(duì)于范圍(3)中的 2–條件為真 也對(duì)本次迭代進(jìn)行同樣的操作
第四次迭代:對(duì)于范圍(3)中的 3–條件為假 因此，它從 Python For Loop 退出
使用 For 循環(huán)對(duì)列表執(zhí)行算術(shù)運(yùn)算
在這個(gè) python 程序中，我們使用 For Loop 來允許用戶為每個(gè)列表輸入自己的元素?cái)?shù)量。
# Python Program for Performing Arithmetic Operations on List
NumList1 = []

Number = int(input("Please enter the Total Number of List Elements: "))
print("Please enter the Items of a First and Second List ")
for i in range(1, Number + 1):
List1value = int(input("Please enter the %d Element of List1 : " %i))
NumList1.append(List1value)
List2value = int(input("Please enter the %d Element of List2 : " %i))
NumList2.append(List2value)
for j in range(Number):
add.append( NumList1[j] + NumList2[j])

The List Items after Addition = [12, 23, 34]
The List Items after Subtraction = [8, 17, 26]
The List Items after Multiplication = [20, 60, 120]
The List Items after Division = [5.0, 6.666666666666667, 7.5]
The List Items after Modulus = [0, 2, 2]
The List Items after Exponent = [100, 8000, 810000]使用 While 循環(huán)對(duì)列表執(zhí)行算術(shù)運(yùn)算
這個(gè) Python 程序用于列表上的算術(shù)運(yùn)算，和上面一樣。我們剛剛將 For 循環(huán)替換為 While 循環(huán)。
