简单的数学加法

Question

所以我只想做一些简单的数学加法从第一个文件中获取数字（假设它是 1）和第二个文件中的数字（假设它是 2）所以我得到的是 12，而不是 3 我真的很感激帮助。

myfile = open('file.txt', "r")
onecaracter = myfile.read(2)
with open('liczba1.txt', 'w') as f:
print(onecaracter, file=f)

myfile = open('file.txt', "r")
twocaracter = myfile.read(myfile.seek(4))

with open('liczba22.txt', 'w') as f:
print(twocaracter, file=f)

with open('liczba1.txt', "r") as file:
z = file.read(1)

with open('liczba22.txt', "r") as fil:
b = fil.read(1)

print(z + b)

Answer 1

变量z和b可能是str类型，并且+运算符在str类型上定义为连接。 您可以将这两个变量转换为整数，它们应该按照您的预期添加，即：

print(int(z) + int(b))

为了说明这一点，您始终可以打印出变量的类型：

print(type(z))

Answer 2

myfile = open('file.txt', "r")
onecaracter = myfile.read(2)
with open('liczba1.txt', 'w') as f:
print(onecaracter, file=f)

myfile = open('file.txt', "r")
twocaracter = myfile.read(myfile.seek(4))

with open('liczba22.txt', 'w') as f:
print(twocaracter, file=f)

with open('liczba1.txt', "r") as file:
z = file.read(1)

with open('liczba22.txt', "r") as fil:
b = fil.read(1)

print(int(z) + int(b))

Answer 3

你应该做一个类型转换：

total = int(z) + int(b)
print(total)
