How to get ASCII value of char in Python?
**To get the ASCII value of a character in Python, you can simply use the built-in ord() function. This function takes a character as an argument and returns its ASCII value.**
For example, if you want to find the ASCII value of the character ‘A’, you can do this:
“`python
print(ord(‘A’)) # Output: 65
“`
This will print 65, which is the ASCII value of the character ‘A’.
FAQs:
1. How can I get the ASCII value of a character in Python?
You can use the ord() function in Python to get the ASCII value of a character.
2. Can I get the ASCII value of a non-ASCII character using the ord() function?
Yes, you can get the ASCII value of any character using the ord() function, but keep in mind that non-ASCII characters may have different values.
3. How do I convert a string to ASCII values in Python?
You can use a list comprehension to convert a string to a list of ASCII values, like this:
“`python
ascii_values = [ord(char) for char in ‘hello’]
print(ascii_values) # Output: [104, 101, 108, 108, 111]
“`
4. Is there a way to get the ASCII value of all characters in a string at once in Python?
Yes, you can use the map() function along with ord() to get the ASCII values of all characters in a string, like this:
“`python
ascii_values = list(map(ord, ‘hello’))
print(ascii_values) # Output: [104, 101, 108, 108, 111]
“`
5. Can I convert ASCII values back to characters in Python?
Yes, you can use the chr() function in Python to convert ASCII values back to characters.
6. How can I convert a list of ASCII values back to a string in Python?
You can use a list comprehension along with the chr() function to convert a list of ASCII values back to a string, like this:
“`python
chars = [chr(ascii_val) for ascii_val in [104, 101, 108, 108, 111]]
print(”.join(chars)) # Output: hello
“`
7. Can I get the ASCII value of a character in a different base in Python?
No, the ord() function in Python always returns the ASCII value in base 10.
8. How do I handle Unicode characters when getting ASCII values in Python?
The ord() function will return the Unicode code point of a character, which can be different from the ASCII value. Make sure to handle Unicode characters properly in your code.
9. Are ASCII values always positive in Python?
Yes, ASCII values in Python are always positive, ranging from 0 to 127.
10. Can I use the chr() function to get characters from Unicode code points in Python?
Yes, you can use the chr() function to get characters from Unicode code points, just like you would for ASCII values.
11. Is it possible to get the hexadecimal or binary representation of an ASCII value in Python?
Yes, you can use the hex() and bin() functions in Python to get the hexadecimal and binary representation of an ASCII value, respectively.
12. How can I get the ASCII value of a character without using the ord() function in Python?
While the ord() function is the most common way to get the ASCII value of a character, you can also create a dictionary mapping characters to their ASCII values and look up the value using the character as the key.
