如果你想顯示x，下面的代碼就足夠了：你可以將字母的大小相差N，盡量避免硬編碼一些任意數(shù)字。
N = 8
# starting from the 1st row and ending at the 8th row
for row in range(1, N):
# within each row, starting from the 1st col and ending in the 8th col
for col in range(1, N):
# decide what to print at the current location
if row == col or row == N-col:
print("X", end="")
else:
print("O", end="")
# go onto the next row
print()

正如您所看到的，您的邏輯不會(huì)執(zhí)行任何插入第二個(gè)操作X。
for row in range (1, 8): ... elif((row + 1)) == 0:
由于 row 采用 0-7 范圍內(nèi)的值，因此這是不可能的：僅當(dāng) 時(shí)才為 true row = -1。是的，Python 允許您從右側(cè)對(duì)列表進(jìn)行索引，但用作索引的變量不會(huì)自動(dòng)采用第二個(gè)值來(lái)滿(mǎn)足這些語(yǔ)義。您必須明確地為其指定一個(gè)值。
您需要重寫(xiě)您的條件以row與最終索引進(jìn)行比較，并且您必須涉及col，就像您對(duì)主對(duì)角線所做的那樣。

您可以將字符串轉(zhuǎn)換為列表，并根據(jù)字符串的長(zhǎng)度和當(dāng)前的 i 使更改對(duì)稱(chēng)
LEN = 7#length of string
string = ""
#initialize string
for i in range(LEN):
string += "O"
#change and print
for i in range(LEN):
new_string = list(string)#from string to list
new_string[i] = "X"#change the i
new_string[LEN-i-1] = "X"#symmetrical change
new_string = "".join(new_string)#list to string
print(new_string)
您可以根據(jù)需要更改 LEN 和字符
