output correction using print() function - afefDXCTN - Aug-10-2020
HI everyone , can you help me to solve this task please specially the first question for others
print(" *")
print(" * *")
print(" * *")
print(" * *")
print("*** ***")
print(" * *")
print(" * *")
print(" *****")
Try to:
minimize the number of print() function invocations by inserting the \n sequence into the strings
make the arrow twice as large (but keep the proportions)
duplicate the arrow, placing both arrows side by side; note: a string may be multiplied by using the following trick: "string" * 2 will produce "stringstring" (we'll tell you more about it soon)
remove any of the quotes, and look carefully at Python's response; pay attention to where Python sees an error - is this the place where the error really exists?
do the same with some of the parentheses;
change any of the print words into something else, differing only in case (e.g., Print) - what happens now?
replace some of the quotes with apostrophes; watch what happens carefully.

As far as understand this, you would only need 1 print statement.
Either concatenate everything into 1 string mixed with the '\n' ,
or make a list of the words, and print in a for loop.

Here are some of my answers, I am sure there are better ones, but they do the trick.
#Original

#Making the arrow twice as large (Keeping the proportions)

print(" * "," * ",sep=2*" ")
print(" * "," * ",sep=2*" ")
print("*** "," *** ",sep=2*" ")
print(" * "," * ",sep=2*" ")
print(" * "," * ",sep=2*" ")
print(" **","*** ",sep=2*"*") #<-- Add as many "*" as necessary inside sep argument
#Duplicating the arrow placing both side by side
print(2*" * ") #<-- Add spaces after, otherwise the duplication will distort the arrow
print(2*" * * ")
print(2*" * * ")
print(2*" * * ")
print(2*"*** *** ")
print(2*" * * ")
print(2*" * * ")
print(2*" ***** ")The final questions are for you to get familiar to Python's error and warning messages.

To Make the arrow twice as large, you just need to convert every character of your string into a string, including the empty ones (spaces)
print(" "," "," "," ","*")
print(" "," "," ","*"," ","*")
print(" "," ","*"," "," "," ","*")
print(" ","*"," "," "," "," "," ","*")
print("*","*","*"," "," "," ","*","*","*")
print(" "," ","*"," "," "," ","*")
print(" "," ","*"," "," "," ","*")
print(" "," ","*","*","*","*","*")
This will add a space between each character and make it twice as large, and you won't have distortion problem
