I have a dataframe where each row is a CAN message which has to be in hex. But when I put the rows into a list, individual values are stored as strings. For example:
['0x0', '0x0', '0x0', '0x0', '0x0', '0x0', '0x0', '0x1']
Is there a way to have [0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x1] instead?
Easy enough! Use the base parameter on the int function to convert from hex string to integer, and you can use hex to go back from integer to hex string.
# Convert hex string to int
str_vals = ['0x0', '0x0', '0x0', '0x0', '0x0', '0x0', '0x0', '0x1']
int_vals = [int(val, 16) for val in str_vals]
# Convert int to hex string
int_vals = [0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x1]
str_vals = [hex(val) for val in int_vals]
