Can We do a conditional block in Python using lists?

Question

Like: if num in Colors[]

Without to put a indexed number in him

Answer 1

Yes, you can do it.
Example is below:

color = ['red', 'blue', 'green', 'pink']
num = 'red'
if num in color:
print('It is there.')
else:
print('Sorry, not there.')

Answer 2

Simon Sauter Like: variable = variable_n in color

But I don't know if the variable will take variable_n, and not do a boolean value 🤔

Answer 3

cat do Chrome I tried what you said. variable = variable_n in color

But it was not working and I don't why it is not working.

Answer 4

You can use any expression in an if (or elif) clause that evaluates to a boolean (True or False) or to something that Python can implicitly convert to a boolean.

Answer 5

You can either use the expression directly in the if clause or you can assign it to a variable first and use the variable in the if clause. So
if n in color:
does the same as
x = n in color
if x:

Answer 6

#You can do it like this:
color = ['red', 'blue', 'green', 'pink']
num = 'red'
boolean = num in color
if boolean:
print('It is there.')
else:
print('Sorry, not there.')
