How can I compile Python to WebAssembly (WASM)?

I’ve read that it’s possible to convert Python 2.7 code to WebAssembly, but I haven’t found a clear, definitive guide on how to do so.

So far, I have successfully compiled a C program to WebAssembly using Emscripten and all its necessary components, and I followed the guide provided on the official WebAssembly website (I want to… - WebAssembly).

Now, I want to know the steps I must follow to achieve the same for Python on an Ubuntu machine. Do I need to convert the Python code to LLVM bitcode first, and then compile it using Emscripten? If so, how can I achieve this conversion from Python to WASM effectively?

Hi,

You can explicitly convert the integer to a string using Python’s str() function and concatenate it with the string.

for i in range(1, 11):
    string = "string" + str(i)
    print(string)

By using str(i), the integer is converted into a string format that seamlessly works with the + operator for concatenation.

F-strings (formatted string literals) allow you to embed expressions directly into a string, making it easy to append integers to strings.

for i in range(1, 11):
    string = f"string{i}"
    print(string)

The use of f"string{i}" ensures that the integer i is automatically converted to a string and inserted in the desired position.

The format() method can also handle concatenation by replacing placeholders within the string.

for i in range(1, 11):
    string = "string{}".format(i)
    print(string)

Here, “string{}”.format(i) replaces the {} placeholder with the integer value of i, effectively appending it to the string.
