How can I write the equivalent to this without the print (f …) without defining 50 as a variable so pre 3.6?
calc_to_units = 24 * 60 * 60
name_of_unit = seconds
print(f”50 days are {50 * calc_to_units} {name_of_unit}”)
Thank you
My attempts were to try to convert 50 to a string which did not work or make sense to me since need a number for the calculation.
the format() method is used to substitute the values of the days, days * calc_to_units, and name_of_unit variables into the string template. The {0}, {1}, and {2} are placeholders for the values that will be substituted in the order they are provided in the format() method.
you need to define the days variable explicitly in this code, as you can't use the value directly in the format() method call.

Trying to make a for loop work in Python I came across a variable declared with "".
i.e: res=""
What is the purpose of the quotes?
Want to know what happens in there.
res="" is an empty string. This can be used later to, for example:
Add another string to it: res += "ABC"
Check whether there is a result. An empty string returns False, while a string with at least 1 character returns True.
Check the length of the string by len(res).
I could go on but you get the point. It's a placeholder.

I wrote what should show if 2 is called in the if command in Python, but it doesn't work.
if baslangic == 2:
print("meslekler:",meslekler)
When you're using input to read in the value of baslangic, it will be a string by default.
Comparing a string to a an integer will never be True ('2' vs 2 - one is a numeric value, the other is a sequence of characters), so you'll have to convert them to the same format.
Either use int(input('Foo? ')) to convert the input to an int when you read it (if the user is only expected to type in an integer), or compare it to a string:
if baslangic == '2':

I need to pass a variable '3-123' to a method in python, but if I do str(3-123) I get '-120'. Tried iterating, but I got an error cause it's an int.
You simply pass the string "3-123".
Your expression str(3-123) tells Python to first evaluate what is in parentheses, which is very clearly the arithmetic expression 3-123. That evaluation mandates a subtraction.
UPDATE PER USER COMMENT
Since you just got it returned from REST, then it's already a string. It seems that your problem is that you're building an expression string to be evaluated in SQL. In this case, you need to build the string you're going to send to SQL, at the character level. For this one item you would extend your 3-123 string with quotation marks:
from_rest = "3-123" # In practice, this comes directly from your REST return value.
to_sql = '"' + from_rest + '"'
This leaves you with a variable that contains the string "3-123" -- seven characters, rather than the original five.
Is that what you needed?

eg-In this instead of using 21 (a value), I want to use a variable to generalize it
print("{:-^21}".format(".|."*(2*(i+1)-1)))
I want to use something like this
print("{:-^M}".format(".|."*(2*(i+1)-1)))
That can easily enough be done. For example:
M = 40
i = 3
print("{val:-^{width}}".format(width=M, val=".|."*(2*(i+1)-1)))
Outputs:
---------.|..|..|..|..|..|..|.----------
You could also do it with f-strings (note the outer ' because " is used on the inner expression):
print(f'{".|."*(2*(i+1)-1):-^{M}}')

I want to add a error message if it exceeds 12 or if a character is entered without any if statements. here is what I have written so far:
import calender
def get_mont_name(month_number):
try:
return calender.month_name[month_number]
except IndexError:
print("'[]' is not a valid month number".format(month_number))
Your code is really close to working!
Firstly, you've spelt calendar wrong, but I assume this is just a typo.
You've slightly misused format() which is probably causing your issue. Replacing your print statement with the following should fix it:
print("{num} is not a valid month number".format(num = month_number))
The curly brackets allow the format() method to identify the parts of the string you'd like to modify.
I hope this helps!
