python print format函数的对齐与宽度设置技巧有哪些

1. 左对齐：使用’<’

name = "John"
age = 25
print("{:<10} is {} years old".format(name, age))

2. 右对齐：使用’>’

name = "John"
age = 25
print("{:>10} is {} years old".format(name, age))

3. 居中对齐：使用’^’

name = "John"
age = 25
print("{:^10} is {} years old".format(name, age))

4. 设置宽度：使用数字指定宽度

name = "John"
age = 25
print("{:20} is {} years old".format(name, age))

5. 设置填充字符：使用指定填充字符

name = "John"
age = 25
print("{:_<10} is {} years old".format(name, age))

6. 设置精度：使用’.’

pi = 3.14159
print("{:.2f}".format(pi))
