Hey guys i have a trouble when i want to add two binaries numbers in Python, i mean i can enter a chain of character in a form of a string but i don't know how to select a specific value in the chain. Here is my code:

```chaina = input('Enter your first binary number')
chainb = input('Enter your second binary number')
liste = str()
r = 0
for i in range [-1,chaina]:
t = 0
t = chaina() + chainb() + r
if t == 2 :
r = 1
liste = str(t) + liste
elif t == 0 or t == 1:
r = 0
liste = str(t) + liste
```

Why don't you simply convert them into decimal and add them as you would do with decimals:

```y = '0b101010'
z = '0b101010'

print(int(y,2) + int(z,2))
print(bin((int(y,2) + int(z,2))))
```

Python: Add two binary numbers, int allows you to specify what base the first argument is in when converting from a string (in this case two), and bin converts a number back to a binary string. Python Challenges: Add two binary numbers Last update on February 26 2020 08:09:27 (UTC/GMT +8 hours)

To add two binary numbers `chaina` and `chainb`:

```bin(eval('0b{} + 0b{}'.format(chaina, chainb)))
```

Or, if you want the binary number without the leading `'0b'`:

```format(eval('0b{} + 0b{}'.format(chaina, chainb)), 'b')
```
##### Explanation

Assume for illustration that `chaina = '1010'` and `chainb = '1111'`. Then:

```>>> '0b{} + 0b{}'.format(chaina, chainb)
'0b1010 + 0b1111'
```

By applying `eval()` on this string, we get the same result as if we typed the expression `0b1010 + 0b1111` directly into Python console.

```>>> 0b1010 + 0b1111
25
>>> eval('0b1010 + 0b1111')
25
```

Finally, `bin()` produces a binary representation of the number passed to it as an argument:

```>>> bin(25)
'0b11001'
```

The same thing is accomplished by calling `format()` with a `'b'` argument:

```>>> format(25, 'b')
'11001'
```

All put together, we are getting the expressions shown above.

Need help in adding binary numbers in python, If sum becomes more than 1, then store carry for next digits. C++; Java; Python3; C#; PHP.

A couple of suggestions

1. normalize the lengths of the bit strings

```l0, l1 = map(len, (str0, str1))
if l0 < l1:
str0 = "0"*(l1-l0) + str0
elif l1 < l0:
str1 = "0"*(l0-l1) + str1
```
2. do a loop on the reversed strings elements and construct the binary string bottom up

```remainder = 0
result = ""
for bit_0, bit1 in zip(reversed(str0), reversed(str1)):
bit_0, bit_1 = map(int, (bit_0, bit_1))
new_bit, remainder = f(bit_0, bit_1, remainder)
result = str(new_bit) + result
if remainder != 0
...
```

writing `f(bit_0, bit_1, remainder)` and treating what to do if `remainder` is not null at the end of the loop is left as an exercise.

The Binary Addition Algorithm, Take input of the two binary numbers as string using the input function. 2. convert them 4. convert the sum into binary using the bin function. PythonProgramming If you have binary numbers as strings, you can convert them to ints first using int (str, base) by providing the base as 2. Then add the numbers like you'd normally do. Finally convert it back to a string using the bin function.

How to take two's complement in Python, If you have binary numbers as strings, you can convert them to ints first using int(​str, base) by providing the base as 2. Then add the numbers  This is a long video, it covers how to take two binary numbers and add them. We have a very VERY easy method in the first 10 minutes of the video, and a more complicated method after.

Program to add two binary strings, Take input of the two binary numbers as string using the input function. 2. convert them into integers using int function passing the base 2 3. Add the integers ^ Binary XOR: It copies the bit if it is set in one operand but not both. (a ^ b) = 49 (means 0011 0001) ~ Binary Ones Complement: It is unary and has the effect of 'flipping' bits. (~a ) = -61 (means 1100 0011 in 2's complement form due to a signed binary number. << Binary Left Shift

• `str is not callable`...? What are you expecting to happen from `chaina()`?
• Also, `range [-1,chaina]` is not valid Python. What would you like to accomplish by this?
