This tutorial introduces how to convert an integer to binary in Python. This tutorial also lists some example codes to elaborate on different ways of conversion from int to binary in Python.
Use bin() Function to Convert Int to Binary in Python
In Python, you can use a built-in function, bin() to convert an integer to binary. The bin() function takes an integer as its parameter and returns its equivalent binary string prefixed with 0b.
An example of this is:
binary = bin(16)
print(binary)
Output:
0b10000
Use format Function to Convert Int to Binary in Python
As shown above, the binary of an integer can be simply obtained with bin(x) method. But if you want to remove the 0b prefix from its output, you can use the format function and format the output.
format(value, format_spec) function has two parameters - value and format_spec. It will return the formatted output according to the format_spec. Below are some example formatting types that can be used inside the placeholders:
| Formatting Type | Role |
|---|---|
= |
Places the sign to the leftmost position |
b |
Converts the value into equivalent binary |
o |
Converts value to octal format |
x |
Converts value to Hex format |
d |
Converts the given value to decimal |
E |
Scientific format, with an E in Uppercase |
X |
Converts value to Hex format in upper case |
And there are many more formatting types available. As we want to convert int to binary, so b formatting type will be used.
Below is the code example.
temp = format(10, "b")
print(temp)
Output:
1010
Use the str.format() Method to Convert Int to Binary in Python
The str.format() method is similar to the format() function above and they share the same format_spec.
Example code to convert int to binary using the str.format() method is below.
temp = "{0:b}".format(15)
print(temp)
Output:
1111
