Python 3 TypeError:未在字符串格式化期间转换所有参数，列出问题

name = "Alice"
age = 30
print("My name is %s and I am %d years old." % (name, age))

print("My name is %s and I am %d years old." % (name))  # 缺少一个参数

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

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

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

name = "Alice"
age = 30
print("My name is %s and I am %d years old." % (name, age))  # 正确

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

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