0026-python实践笔记：批量定义全局变量

目录

1.遍历列表的每个元素，使之成为全局变量，并生成元素指向的字典

2. 生成全局变量字典，字典值列表储存

3.生成一个全局变量字典

4.受列表 t 元素个数生成3个‘day’字典

5.生成键为'day'的全局变量字典

6.遍历列表生成全局变量列表字典

1.遍历列表的每个元素，使之成为全局变量，并生成元素指向的字典

t = ['one','two','three']
for i in t:
    globals() [i] = {}

print(i)
print(globals())

2. 生成全局变量字典，字典值列表储存

t = ['one']
for i in t:
    globals() [i] = {}
    globals() [i]['day'] = []

print(i)
print(globals())

3.生成一个全局变量字典

t = ['one']
for i in t:
    globals() [i] = {}
    globals() [i]['day'] = []
    for k in range(3):
        globals()[i]['day'].append(k)
        print(i)

print(i)
print(t)
print(globals())

4.受列表 t 元素个数生成3个‘day’字典

t = ['one','two','three']
for i in t:
    globals() [i] = {}
    globals() [i]['day'] = []
    for k in range(3):
        globals()[i]['day'].append(k)
        print(i)

print(i)
print(t)
print(globals())

5.生成键为'day'的全局变量字典

def fun():
    s = ['SH']
    for i in s:
        globals() [i] = {}
        globals() [i]['day'] = []
        for k in range(7):
            globals()[i]['day'].append(k)
    return SH

print(fun())
print(globals())

6.遍历列表生成全局变量列表字典

s = ['one','two','three']
def fun(a):
    s = ['SH']
    for i in s:
        globals() [i] = {}
        globals() [i][a] = []
        for k in range(3):
            globals()[i][a].append(0)
    return SH

list = []
for i in s:
    list.append(fun(i))
print(list)
