print (output)

[naughtyCat]

There are three ways:

command = "Hello World!"

print(f"my command is {command}")
print("my command is %s"%command)
print("my command is {}".format(command))

Output:
my command is Hello World!
my command is Hello World!                                                                          exe c:/Users/steve/Desktop/html/math/sdfdsdf.py
my command is Hello World!
