本文实例为大家分享了python编写简单计算器的具体代码，供大家参考，具体内容如下
做一个计算器，这是我们想要的效果。
1、准备工作
导入time、tqdm、math库
from tqdm import* from time import* from math import*
2、开始
添加一个重复循环并添加变量s
while True:
#清屏
print('\033c')
while True:
#如果用法输入的是str类型将打印输入错误，再次循环
try:
s = int(input('''选择一种计算方式或是退出
1、加法
2、减法
3、乘法
4、除法
5、整除
6、取余
7、乘方
8、退出
请输入你的选择：'''))
break
except:
print('输入错误')
2.2、判断变量s并进行运算
if s == 1:
print('\033c')
print('正在载入......')
#进度条
for i in tqdm(range(1, 500)):
sleep(0.02)
print('完毕！')
sleep(1)
print('\033c')
while True:
try:
calculatorinput1 = int(input('请输入第一个加数：'))
calculatorinput2 = int(input('请输入第二个加数：'))
break
except:
print('输入错误！')
#运算
c = calculatorinput1 + calculatorinput2
print(f'{calculatorinput1}加{calculatorinput2}等于{c}')
sleep(3)
2.3、依次添加减法、乘法、除法、整除、取余、乘方
elif s == 2:
print('\033c')
print('正在载入......')
for i in tqdm(range(1, 500)):
sleep(0.02)
print('完毕！')
sleep(1)
print('\033c')
while True:
try:
calculatorinput1 = int(input('请输入被减数：'))
calculatorinput2 = int(input('请输入减数：'))
break
except:
print('输入错误！')
c = calculatorinput1 - calculatorinput2
print(f'{calculatorinput1}减{calculatorinput2}等于{c}')
sleep(3)
elif s == 3:
print('\033c')
print('正在载入......')
for i in tqdm(range(1, 500)):
sleep(0.02)
print('完毕！')
sleep(1)
print('\033c')
while True:
try:
calculatorinput1 = int(input('请输入第一个乘数：'))
calculatorinput2 = int(input('请输入第二个乘数：'))
break
except:
print('输入错误！')
c = calculatorinput1 * calculatorinput2
print(f'{calculatorinput1}乘{calculatorinput2}等于{c}')
sleep(3)
elif s == 4:
print('\033c')
print('正在载入......')
for i in tqdm(range(1, 500)):
sleep(0.02)
print('完毕！')
sleep(1)
print('\033c')
while True:
try:
calculatorinput1 = int(input('请输入被除数：'))
calculatorinput2 = int(input('请输入除数：'))
break
except:
print('输入错误！')
c = calculatorinput1 / calculatorinput2
print(f'{calculatorinput1}除以{calculatorinput2}等于{c}')
sleep(3)
elif s == 5:
print('\033c')
print('正在载入......')
for i in tqdm(range(1, 500)):
sleep(0.02)
print('完毕！')
sleep(1)
print('\033c')
while True:
try:
calculatorinput1 = int(input('请输入被除数：'))
calculatorinput2 = int(input('请输入除数：'))
break
except:
print('输入错误！')
c = calculatorinput1 // calculatorinput2
print(f'{calculatorinput1}整除{calculatorinput2}等于{c}')
sleep(3)
elif s == 6:
print('\033c')
print('正在载入......')
for i in tqdm(range(1, 500)):
sleep(0.02)
print('完毕！')
sleep(1)
print('\033c')
while True:
try:
calculatorinput1 = int(input('请输入被除数：'))
calculatorinput2 = int(input('请输入除数：'))
break
except:
print('输入错误！')
c = calculatorinput1 % calculatorinput2
print(f'{calculatorinput1}取余{calculatorinput2}等于{c}')
sleep(3)
elif s == 7:
print('\033c')
print('正在载入......')
for i in tqdm(range(1, 500)):
sleep(0.02)
print('完毕！')
sleep(1)
print('\033c')
while True:
try:
calculatorinput1 = int(input('请输入第一个数：'))
calculatorinput2 = int(input('请输入第二个数：'))
break
except:
print('输入错误！')
c = pow(calculatorinput1, calculatorinput2)
print(f'{calculatorinput1}的{calculatorinput2}次方是{c}')
sleep(3)
3、退出
使用break退出循环
elif s == 8: break
3.2、不是选项中的任何数字
else:
print("输入错误")
sleep(2)
4、全部代码
from tqdm import*
from time import*
from math import*
while True:
#清屏
print('\033c')
while True:
#如果用法输入的是str类型将打印输入错误，再次循环
try:
s = int(input('''选择一种计算方式或是退出
1、加法
2、减法
3、乘法
4、除法
5、整除
6、取余
7、乘方
8、退出
