Python 之 编程中常见错误
1 变量名不正确
message = "hello" print(msg) # 错误信息：NameError: name 'msg' is not defined
2 单引号包围的字符串中包含单引号，双引号包围的字符串中包含双引号
message = 'he'llo' print(message) # 错误信息：SyntaxError: invalid syntax message = "he"llo" print(message) # 错误信息：SyntaxError: invalid syntax
3 类型错误
num1 = 1 print(1 + "2") # 错误信息：TypeError: unsupported operand type(s) for +: 'int' and 'str'
4 除0错误
num1 = 1 print(1 / 0) # 错误信息：ZeroDivisionError: division by zero
5 列表下标越界
colors = ["red","blue","yellow"] print(colors[3]) # 错误信息：IndexError: list index out of range
6 for循环后面的代码忘记缩进
colors = ["red", "blue", "yellow", "orange", "white", "pink", "brown"] for color in colors: print(color) #错误信息：IndentationError: expected an indented block
7 不必要的缩进
colors = ["red", "blue", "yellow", "orange", "white", "pink", "brown"] print(colors) # 错误信息：IndentationError: unexpected indent
8 for循环忘了后面的冒号
colors = ["red", "blue", "yellow", "orange", "white", "pink", "brown"] for color in colors print(color) #错误信息：SyntaxError: invalid syntax
9 修改元组中的元素，引发类型错误
# 定义元组，使用圆括号而不是方括号 colors = ("red", "blue", "yellow", "orange", "white", "pink", "brown") # 如果修改元组中的元素，将返回类型错误信息 colors[0] = "black" # 错误信息：TypeError: 'tuple' object does not support item assignment
