Basic Python List Excercise -

how make graph print vertically rather horizontally? please try use same concept(loops, lists) used in code understand changes. thank help!

here code:

sign='x'  test_list=[500000,5000000,7000000] test_calc_list=[] test_sum=sum(test_list)  test_string_list=['test1','test2','test3'] signs_list=[]  x in test_list:     test_calc=round((x/float(test_sum)*10))     test_calc_list.append(test_calc)  y in test_calc_list:     y=int(y)     signs=y*sign     signs_list.append(signs)  z in range(len(test_string_list)):     print "%8s: %-6s %7i"% (test_string_list[z],signs_list[z],test_list[z]) 

this output get:

test1:           500000 test2: xxxx     5000000 test3: xxxxxx   7000000 

this output want:

                      x            x          x            x          x            x          x            x          x test1      test2      test3         500000     5000000    7000000 

assuming isn't homework (you know there software detect plagiarism?) here possible solutions.

easiest assume list fixed size:

for in range(len(max(signs_list)), 0, -1):     print ('{0:<8} {1:<8} {2}').format(         'x' if len(signs_list[0]) >= else '',          'x' if len(signs_list[1]) >= else '',          'x' if len(signs_list[2]) >= else '') print ('{0:<8} {1:<8} {2}').format(test_string_list[0], test_string_list[1], test_string_list[2]) print ('{0:<8} {1:<8} {2}').format(test_list[0], test_list[1], test_list[2]) 

trickier dealing lists of arbitrary size requires eval

for in range(len(max(signs_list)), 0, -1):     template_string = ""     input_string = ""     z in range(len(test_string_list)):         string_part = "{" + str(z) + ":<8} "         template_string += string_part         input_part = "'x' if len(signs_list[" \             + str(z) + "]) >= else '',"         input_string += input_part     statement = "('" + template_string + "')"     statement += ".format"     statement += "(" + input_string[:-1] + ")"     print eval(statement)  template_string = "" input_string = "" z in range(len(test_string_list)):     string_part = "{" + str(z) + ":<8} "     template_string += string_part     input_part = "test_list[" + str(z) + "],"     input_string += input_part statement = "('" + template_string + "')" statement += ".format" statement += "(" + input_string[:-1] + ")" print eval(statement)  template_string = "" input_string = "" z in range(len(test_string_list)):     string_part = "{" + str(z) + ":<8} "     template_string += string_part     input_part = "test_string_list[" + str(z) + "],"     input_string += input_part statement = "('" + template_string + "')" statement += ".format" statement += "(" + input_string[:-1] + ")" print eval(statement) 

the above monstrosity can refactored remove statement construction:

def statement_constructor(list_type, list_size):     template_string = ""     input_string = ""     z in range(list_size):         string_part = "{" + str(z) + ":<8} "         template_string += string_part         if list_type == "signs_list":             input_part = "'x' if len(signs_list[" \                 + str(z) + "]) >= else '',"         else:             input_part = list_type + "[" + str(z) + "],"         input_string += input_part     statement = "('" + template_string + "')"     statement += ".format"     statement += "(" + input_string[:-1] + ")"      return statement  length = len(test_string_list) in range(len(max(signs_list)), 0, -1):     print eval(statement_constructor('signs_list', length)) print eval(statement_constructor('test_list', length)) print eval(statement_constructor('test_string_list', length)) 

all 3 produce same output:

                  x                           x                  x        x                  x        x                  x        x                  x        x         500000   5000000  7000000   test1    test2    test3  

although solution using eval handle test4, test5, , on. there may more elegant solution, works.

edit: or more elegant solution without eval overkill suggested in comment michael0x2a.
