如何在Python语言中修复“TypeError:在字符串格式化过程中不是所有参数都被转换”

# 错误示例
name = "Alice"
age = 30
print("My name is %s and I am %d years old." % (name))  # 缺少一个参数

# 正确示例
print("My name is %s and I am %d years old." % (name, age))

# 使用str.format()方法
print("My name is {} and I am {} years old.".format(name, age))

# 使用f-string
print(f"My name is {name} and I am {age} years old.")

name = "Alice"
age = 30

# 旧式%操作符
try:
    print("My name is %s and I am %d years old." % (name))
except TypeError as e:
    print(f"Error: {e}")

# 正确示例
print("My name is %s and I am %d years old." % (name, age))

# 使用str.format()方法
print("My name is {} and I am {} years old.".format(name, age))

# 使用f-string
print(f"My name is {name} and I am {age} years old.")
