Please what is thé use or This signe //

Question

// , %

Answer 1

To add to William's answer, "//" or the hard division (division with no remainder) sign acts as so:

5 // 2 == 2

because it drops the remainder, (5 / 2 == 2.5)

Answer 2

If you are talking about '%' it is a modulo operator which is basically the remainder of a division operation.

4%2 == 0 because 4 divided by 2 is 2 with zero remainder.

So 4%2+5 == 5

Hope that helps.

Answer 3

Some programming languages use // for comments. This is why it is crucial to 👉mention the relevant programming language.

The operators are also explained in 👉lesson 5 of the sololearn Python Core course. Yiu can re-read them as often as you like.

Answer 4

talking about python

# >>> the character '%' is also used as placeholder for output formatting. (old version)
name = "tom"
age = 28
print("%s is %s years old." % (name, age))
# output is: tom is 28 years old.

# >>> the character '%' is also used with date / time formatting:
from datetime import datetime
time_data = "17/02/22"
format_data = "%d/%m/%y"
print(datetime.strptime(time_data, format_data))
# output is: 2022-02-17 00:00:00
