print(f"...:")-statement too long - 把它分成多行而不弄乱格式

Question

我有一个带有格式化输出的控制台程序。为了始终获得相同长度的打印输出，我有一个相当复杂的格式化打印输出。

print(f"\n{WHITE_BG}{64*'-'}")
print(f"\nDirektvergleich{9*' '}{RED}{players[0].name}{4*' '}{GREEN}vs.{4*' '}{RED}{players[1].name}{CLEAR}\n")
print(f"""{15*'~'}{' '}{YELLOW}Gesamt{CLEAR}:{' '}{players[0].name}{' '}{GREEN}{int(player1_direct_wins)}{(int(4-len(player1_direct_wins)))*' '}-{(int(4-len(player1_direct_losses)))*' '}{int(player1_direct_losses)}{CLEAR}{' '}{players[1].name}{' '}{(28-len(players[0].name)-len(players[1].name))*'~'}\n""")
print(f"""{15*'~'}{' '}{YELLOW}Trend{CLEAR}:{'  '}{players[0].name}{' '}{GREEN}{int(player1_trend_wins)}{(int(4-len(player1_trend_wins)))*' '}-{(int(4-len(player1_trend_losses)))*' '}{int(player1_trend_losses)}{CLEAR}{' '}{players[1].name}{' '}{(28-len(players[0].name)-len(players[1].name))*'~'}""")    
print(f"\n{WHITE_BG}{64*'-'}")

这导致我的 windows cmd 中的以下输出

为了便于阅读，我尝试在多行上打印，因此我在 stackoverflow 上发现了以三引号开头的想法。但是当我在中间剪切这个 print(f"...") 语句时，我搞砸了我的格式。

例子：

print(f"\n{WHITE_BG}{64*'-'}") #als String einspeisen?!
print(f"\nDirektvergleich{9*' '}{RED}{players[0].name}{4*' '}{GREEN}vs.{4*' '}{RED}{players[1].name}{CLEAR}\n")
print(f"""{15*'~'}{' '}{YELLOW}Gesamt{CLEAR}:{' '}{players[0].name}{' '}{GREEN}{int(player1_direct_wins)}{(int(4-len(player1_direct_wins)))*' '}-
    {(int(4-len(player1_direct_losses)))*' '}{int(player1_direct_losses)}{CLEAR}{' '}{players[1].name}{' '}{(28-len(players[0].name)-len(players[1].name))*'~'}\n""")
print(f"""{15*'~'}{' '}{YELLOW}Trend{CLEAR}:{'  '}{players[0].name}{' '}{GREEN}{int(player1_trend_wins)}{(int(4-len(player1_trend_wins)))*' '}-
    {(int(4-len(player1_trend_losses)))*' '}{int(player1_trend_losses)}{CLEAR}{' '}{players[1].name}{' '}{(28-len(players[0].name)-len(players[1].name))*'~'}""")       
print(f"\n{WHITE_BG}{64*'-'}")

导致...

谁能指出我正确的方向如何以显示的方式格式化我的输出，但没有这种荒谬的长行长度。

提前谢谢你们！

三重引号字符串保留换行符，因此它们确实不是您想要的。现在，当它找到两个相邻的字符串时，Python 解析器会自动将它们连接成一个字符串，即：

s = "foo" "bar"

等价于

s = "foobar"

如果你把你的字符串放在括号内，这会起作用：

s = ("foo" "bar")

在这种情况下，您也可以将每个字符串放在自己的行中：

s = (
    "foo"
    "bar"
    )

这也适用于“fstrings”所以你想要的是这样的：

print((
    f"{15*'~'}{' '}{YELLOW}Gesamt{CLEAR}:{' '}{players[0].name}{' '}{GREEN} " 
    f"{int(player1_direct_wins)}{(int(4-len(player1_direct_wins)))*' '}-"
    f"{(int(4-len(player1_direct_losses)))*' '}{int(player1_direct_losses)}"
    f"{CLEAR}{' '}{players[1].name}{' '}{(28-len(players[0].name)-"
    f"len(players[1].name))*'~'}\n"
    ))

话虽如此，我宁愿使用中间变量，也不愿将如此复杂的表达式塞进 fstring 中。
