Python Praw TypeError:在字符串格式化过程中并非所有参数都已转换

name = "Alice"
age = 25

# 错误示例：参数的数量少于占位符的数量
message = "My name is {}, and I am {} years old. {}".format(name, age)
# 正确示例：使用默认值或者空字符串作为占位符的值
message = "My name is {}, and I am {} years old. {}".format(name, age, "")

# 错误示例：参数的数量多于占位符的数量
message = "My name is {}, and I am {} years old.".format(name, age, "Nice to meet you!")
# 正确示例：使用索引或者命名参数来指定要替换的占位符
message = "My name is {0}, and I am {1} years old. {2}".format(name, age, "Nice to meet you!")
message = "My name is {name}, and I am {age} years old. {greeting}".format(name=name, age=age, greeting="Nice to meet you!")
