Answer:





Explanation:
Required
Evaluate each expression
The simple rules to follow are:
(1) All expressions in bracket will be evaluated based on its data type
(2) Divisions will return only integer values
(3) Integers immediately after string values will be concatenated (not added)
So, the results are as follows:

Evaluate till a string is encountered

Followed by "."
Then:

-- because expressions after string operations are concatenated.
So, we have:


Evaluate till a string is encountered


So, we have:


Evaluate till a string is encountered


So, we have:
Evaluate till a string is encountered

--- multiply 2 and 3, then concatenate
So, we have:


Since a string starts the expression, the whole expression will be concatenated except the multiplication and the expressions in bracket.
So, we have:

Answer:
Following are the code to this question can be described as follows:
c= input('Input triangle_char: ') #defining variable c that input character value
length = int(input('Enter triangle_height: ')) # Enter total height of triangle
for i in range(length): # loop for column values
for j in range(i+1): #loop to print row values
print(c,end=' ') #print value
print()# for new line
Output:
please find the attachment.
Explanation:
In the above python code, two variable "c and length" variables are declared, in variable c is used to input char variable value, in the next line, length variable is defined, that accepts total height from the user.
- In the next line, two for loop is declared, it uses as nested looping, in which the outer loop prints column values and inner the loop is used to prints rows.
- To prints all the value the print method is used, which prints the user input character triangle.
Answer:
True.
