How to display a byte array as hex values
(5 answers)
Closed 4 years ago.
In my code I receive a bytearray with the value 0x41 as b'\x41'. Printing this value gives b'A'. How can I print it in such a way that i get the result b'\x41'. (Python 3.7)
Testcode:
print("b'\x41'")
Unfortunately, if you don't like the default display, you have to generate it yourself:
>>> b = b'\x41\x42\x43'
>>> print(b)
b'ABC'
>>> print("b'" + ''.join(f'\\x{c:02x}' for c in b) + "'")
b'\x41\x42\x43'

Closed 4 months ago.
I'm using python formating to print some left aligned columns.
This nicely left alignes a, b and c:
out_string = '{:30} {:20} {:10}'.format(a, b, c)
Then I tried using constants, but failed with ValueError: Invalid format specifier:
ALIGNa = 30
ALIGNb = 20
ALIGNc = 10
out_string = '{:ALIGNa} {:ALIGNb} {:ALIGNc}'.format(a, b, c)
Why does it fail?

I know the question sounds a bit vague, but this should clear it up.
a = "[200, 30.5, 37]" #This is a string literal, where a[0] = '['
b = [200, 30.5, 37] #This is a list literal, where b[0] = 200
How do I get b from a?
b = eval(a)
This should do the trick.

About the changing id of an immutable string
(5 answers)
Closed 5 years ago.
Here's my snippet of code
>>> a = "some_string"
140420665652016
>>> id(a)
>>> id("some" + "_" + "string")
140420665652016
Notice that both the ids are same. But this does not happen with integers (which are also immutable like strings).
>>> a = 999
>>> id(a)
140420666022800
>>> id(999)
140420666021200
>>> id(998 + 1)
140420666023504
I'm not able to find a reason of why it's happening only with strings.

How to Convert a string like '123' to int 1,2 and 3 so that I can perform 1+2+3. I am new to python. Can you please help me? I am not able to split the list. I don't think splitting the string will be of any use as there are no delimiters. Can you help me to understand how can this string elements be separated and treated as intergers?
x = "123"
s = 0
for a in x:
s = int(a) + s

x = "01100001"
How do i convert this string into ASCII
Expected Result:

Use following one liner
x = chr(int('010101010',2))
will work.
