Try this: line = ser.readline().strip() values = line.decode('ascii').split(',') a, b, c = [int(s) for s in values] The call to .strip() removes the trailing newline. Some methods will only be available if the corresponding string method is available in your version of Python.
Some encodings use one byte to store a character, some two and some four. What's the best way to do this? The numpy.char module provides a set of vectorized string operations for arrays of type numpy.string_ or numpy.unicode_.All of them are based on the string methods in …
Convert bytes to a Python string . Convert a number or string x to an integer, or return 0 if no arguments are given. It reads from current bit position pos in the bitstring according the the format string and returns a single result. Go to the editor Sample output: Original Array: ['2' '11' '234' '1234' '12345'] Numeric string of 5 digits with zeros: ['00002' '00011' '00234' '01234' '12345'] Click me to … Win7, 64-bit. The regular rules for writing apply; to get a fixed-width ASCII string, use numpy.string_, and to get a variable-length ASCII string, use bytes. It converts all uppercase characters to lowercase. The call .decode('ascii') converts the raw bytes to a string..split(',') splits the string on commas. This module is used to perform vectorized string operations for arrays of dtype numpy.string_ or numpy.unicode_. import numpy as np a = np.array([1, 256, 8755], dtype = np.int16) print 'Our array is:' print a print 'Representation of data in memory in hexadecimal form:' print map(hex,a) # byteswap() function swaps in place by passing True parameter print 'Applying byteswap() function:' print a.byteswap(True) print 'In hexadecimal form:' print map(hex,a) # We can see the bytes being swapped All of them are based on the standard string functions in Python’s built-in library. This is what arr.byteswap() does. So, when reading or writing scalar string attributes, on Python 3 they will always be returned as type str, regardless of the underlying storage mechanism. This is the role of arr.newbyteorder() Change the byte-ordering of the underlying data, leaving the dtype interpretation as it was. int:n n bits as a signed integer. When creates a 'bytes' object from a numpy array of length 1, the result is a 'bytes' string with the length of the value of the single element, not a single byte equal to the single element.
import numpy as np a = np.array([1, 256, 8755], dtype = np.int16) print 'Our array is:' print a print 'Representation of data in memory in hexadecimal form:' print map(hex,a) # byteswap() function swaps in place by passing True parameter print 'Applying byteswap() function:' print a.byteswap(True) print 'In hexadecimal form:' print map(hex,a) # We can see the bytes being swapped Write a NumPy program to make all the elements of a given string to a numeric string of 5 digits with zeros on its left.
Starting from numpy 1.4, if one needs arrays of strings, it is recommended to use arrays of 'dtype' 'object_', 'string_' or 'unicode_', and use the free functions in the 'numpy.char' module for fast vectorized string operations.
Change the byte-ordering information in the array dtype so that it interprets the underlying data as being in a different byte order. ... For Python 3,this is a much safer and Pythonic approach to convert from byte to string: ... Understanding numpy 2D histogram – Stack Overflow . Posted by: admin October 29, 2017 Leave a comment. Size of the data (how many bytes is in e.g.
int() - constructs an integer number from an integer literal, a float literal (by rounding down to the previous whole number), or a string literal (providing the string represents a whole number) float() - constructs a float number from an integer literal, a float literal or a string literal (providing the string represents a …
It calls str.lower for each element. Finally the call [int(s) for s in value] is called a list comprehension, and produces a list of integers. This is what arr.byteswap() does. Change the byte-ordering information in the array dtype so that it interprets the underlying data as being in a different byte order.

Some methods will only be available if the corresponding string method is available in your version of Python.
You can vote up the examples you like or vote down the ones you don't like. But how characters are stored can vary. The following are code examples for showing how to use numpy.bytes_(). tested with numpy 1.6.2, python 3.2.3. python - create - Convert a numpy.ndarray to string(or bytes) and convert it back to numpy.ndarray . This is the role of arr.newbyteorder() Change the byte-ordering of the underlying data, leaving the dtype interpretation as it was.
