python 循环语句下载

以下是Python中两种循环语句的基本用法和示例代码：
1. for循环

# 遍历列表
fruits = ['apple', 'banana', 'orange']
for fruit in fruits:
    print(fruit)

# 遍历字符串
for char in 'hello':
    print(char)

# 遍历字典
dict = {'name': 'Tom', 'age': 18}
for key, value in dict.items():
    print(key, value)

2. while循环

# 计算1到100的和
sum = 0
i = 1
while i <= 100:
    sum += i
    i += 1
print(sum)
