当我运行下面的代码时，迭代从 0 开始。我想将行更改为从第 1 行开始。我该如何更改它？我尝试在迭代开始前输入 rownum=1。
代码:
def triangle(rows):
for rownum in range (rows):
PrintingList = list()
print ("Row no. %i" % rownum)
for iteration in range (rownum):
newValue = input("Please enter the %d number:" %iteration)
PrintingList.append(int(newValue))
print()
def routes(rows,current_row=0,start=0):
for i,num in enumerate(rows[current_row]): #gets the index and number of each number in the row
if abs(i-start) > 1: # Checks if it is within 1 number radius, if not it skips this one. Use if not (0 <= (i-start) < 2) to check in pyramid
continue
if current_row == len(rows) - 1: # We are iterating through the last row so simply yield the number as it has no children
yield [num]
else:
for child in routes(rows,current_row+1,i): #This is not the last row so get all children of this number and yield them
yield [num] + child
numOfTries = input("Please enter the number of tries:")
Tries = int(numOfTries)
for count in range(Tries):
numstr= input("Please enter the height:")
rows = int(numstr)
triangle(rows)
routes(triangle)
max(routes(triangle),key=sum)
输出:
Please enter the number of tries:2
Please enter the height:4
Row no. 0
Row no. 1
Please enter the 0 number:
感谢任何帮助。
请您参考如下方法:
改变:
for rownum in range (rows):
到:
for rownum in range (1, rows+1):
