In Python, the '-' symbol has various uses. Here are some common applications: 1. Subtraction: The '-' operator can be used for subtraction, for example:
a = 5
b = 3
c = a - b
print(c) # Output will be 2
- Negation: In Python, '-' can also represent negation, such as:
a = -5
print(a) # Output will be -5
- Negative Sign: In mathematical expressions, '-' indicates a negative value, for instance:
a = -10
b = -a # b's value will be 10
- Comments: In Python, '#' is used to denote comments; however, it's worth noting that while '-' itself isn't used for comments directly, it plays a role in indicating negative values or operations. For example:
# This is a comment and won't execute.
printf("Hello, world!") # This is also a comment.
It's important to understand that the meaning of '-' may vary depending on the context.
