Python条件if语句

我是python的初学者，在学习python的过程中，我在执行

if

语句时出错

有人能告诉我代码中遗漏了什么吗

文件“Demo\u class2\u Conditions.py”，第8行
打印（X）

缩进错误：应为缩进块

您应该始终在条件之后缩进属于块的语句（2或4个空格）

您的示例可以正确缩进，如下所示：

# first evaluation starts with no indentation
if X > Y: 
  print(X) # single statement (block 1) if previous condition satisfied
else:
  # block 2 begins
  print(Y)
  # block 2 ends

# second evaluation starts with no indentation
if Y > Z:
  print(Y) # block 3 has only 1 statement
else:
  print(Z) # single statement is block 4

# everything after evaluating is not indented

# first evaluation starts with no indentation
if X > Y: 
  print(X) # single statement (block 1) if previous condition satisfied
else:
  # block 2 begins
  print(Y)
  # block 2 ends

# second evaluation starts with no indentation
if Y > Z:
  print(Y) # block 3 has only 1 statement
else:
  print(Z) # single statement is block 4

# everything after evaluating is not indented
