Python错误: SyntaxError: Non-ASCII character解决办法
1.
```
import pandas as pd # 导入pandas库,起别名为pd
```
2.
```
for i in range(10): # 使用for循环,循环变量i从0到9
print(i) # 在循环中打印i的值
```
3.
```
def add(x, y): # 定义一个函数add,需要两个参数x和y
return x + y # 返回x和y的和
```
4.
```
a = 1 # 定义变量a为整数1
b = 2 # 定义变量b为整数2
c = a + b # 将a和b相加,结果赋值给变量c
```
5.
```
if x > y: # 如果x大于y
print('x is greater than y') # 则打印'x is greater than y'
else: # 否则
print('x is less than or equal to y') # 打印'x is less than or equal to y'
```
